Tornado Alley In The US

The US is a big nation. It is not only made up of 50 states and a handful of territories but it is likewise a big chunk of land mass that experiences all four seasons each year. On the average, roughly 1,200 tornadoes hit the US annually especially in the East Rocky Mountains as well as in the Midwest, the Great Plains, the South of the US and the Mississippi Valley. The term “Tornado Alley” is a tornado-prone part of the US that stretches from the north of Texas to Canada, the center of which is in Oklahoma and Kansas. It’s probably the reason for the plot of the infamous Wizard of Oz. In the south of US, they have the Dixie Alley that is also made of states often hit by tornadoes.

Tornadoes often form during spring since the climate transitions from cool to warm and not so during winter. The months of March to June are known as the US tornado season. People living in high-risk states should be more vigilant than ever since tornadoes can form without warning. Modern technology also does its part in helping people survive tornadoes in one piece.

Tornadoes ripped through southern Louisiana on Tuesday, leaving only splintered wood where houses once stood and causing dozens of minor injuries as a violent weather system barreled across the South.

There were no immediate reports of deaths after four tornadoes hit the region, leaving 10,000 homes without power and prompting Louisiana Gov. John Bel Edwards to declare a state of emergency. Dozens of homes, cars and businesses were damaged.

The worst of the devastation occurred in New Orleans East, where a tornado ripped buildings from foundations and left power lines dangerously strewn across roadways. James Thomas rode out the storm there in his bathroom after grabbing his motorcycle helmet for extra protection. After the danger passed, he emerged to find his house narrowly escaped the path of the tornado, which left his neighborhood encased in damage.

"It's bad," he told the Associated Press. "I've never seen it this bad."

Twisters are a sight to behold. Many are captivated by tornadoes that some even make it a hobby to pursue them. However, let us not forget how destructive its nature is and lives are lost and properties are decimated in just one strike. Those living in states that are in the path of these deadly tornadoes have learned from a young age how to prepare for when it strikes and periodic tornado drills are also practiced to increase awareness and limit casualties.

A series of outbreaks that began in January has propelled the preliminary 2017 U.S. tornado count to its highest level for mid-March in nearly a decade.

Two dozen people have lost their lives from tornadoes so far this year, and the waves of severe weather have contributed to economic losses of more than $2 billion.

The preliminary tornado count for the year was 309 through March 20, according to Dr. Greg Forbes, severe weather expert at The Weather Channel. That is the largest number of tornadoes to this point in the season since March 2008, which had 327 tornadoes by that date. 

January's tornado count of 133 was more than triple the 20-year average of 40 for that month. A preliminary count of 112 tornadoes have touched down so far in March, and that already exceeds the entire month's 20-year average of 76.

The United States have witnessed the most number of tornadoes throughout the world. So, knowing that you are in the path of these natural mammoth vacuums in the sky, it is only practical to master what to do when it comes. It is best if you can set up a basement or underground dwelling as your safe haven when tornadoes hit your area. Always try to go to the lowest part of a structure if you are in a building, it can be the center of the hallway and not necessarily the lowest floor. Participating in routine tornado drills is the best preparation of all as you learn in details what to do and what to avoid during tornado season.

China: Air Pollution At Its Worst

Air is crucial to life. We will die without air. That’s quite obvious. However, we may also gradually die from overexposure to air pollution. Our body needs clean air now more than ever especially that rapid urbanization has left most cities polluted and smog-filled. Air pollution is actually our fault. We were too consumed by our fascination with technology that we forgot to take into consideration its impact to the environment, especially to the very air we breathe.

If there is any other place on the planet that is known for extreme air pollution issues, it would have to be China. The most populous country in the planet, many Chinese are facing each day in a world full-of smog and polluted air. While we may not entirely get rid of air pollutants, they should be at an acceptable level so as not to pose health risks to everyone. It is why it’s not uncommon to see individuals walking the streets wearing face masks because it is virtually impossible to breathe clean air in most major Chinese cities.

The central government declared war on pollution in China four years ago, but progress has been limited.

The environment ministry said last week it found that thousands of polluters had faked emissions data or resisted checks made by inspectors from mid February to mid March.

The three-month average reading in the 28 cities of PM 2.5, the small particles in smog deemed most harmful to health, was 103 micrograms per cubic metres, the ministry said. This was a rise of 12 per cent from a year earlier.

Readings over 101 are ranked as unhealthy for sensitive groups and members of the public are urged to limit the amount of time they exercise outdoors.

Levels of PM10, slightly larger particles of pollutants, averaged 160 micrograms per cubic metres in the cities from January to March, unchanged from the same period last year, the ministry said.

The ministry said in a separate notice published on Wednesday that it would send 5,600 inspectors on a year-long investigation into the sources of air pollution in major northern cities, the largest such campaign ever undertaken nationally.

If California is the most polluted state in the United States, China earned the title in the whole world. And millions of Chinese live in this unhealthy environment despite the government’s effort to address air pollution issues. The Chinese government is intensifying their efforts but the threat remains the same and is probably worsened by other equally controversial topics like climate change and global warming.

China experiences one of the highest rates of air pollution in the world. The quality of air remains poor in its cities and industrial towns for most part of the year. A new research published in journal Science Advances has said that part of the reason for this is changing weather.

The paper studied the climatic conditions and air pollution in China and found that poor air quality continued due to extremely poor ventilation conditions, which were caused by Arctic sea ice loss and the weather changes that followed.

Scientists studied China’s climatic condition from January 2013 using satellite data and visibility measures. As per the paper, January 2013 saw unprecedented large-scale haze that continued for almost an entire month. During this so-called “airpocalypse” period, close to 70 per cent of the 74 major cities exceeded the daily PM2.5 ambient air quality standard of China.

The researchers also analysed sea ice, snowfall and large-scale weather patterns. They found a connection between stagnant air conditions and Arctic sea ice concentration, snow cover in Eurasia,   El Niño/Southern Oscillation, and others. Climate change plays a role in changes in these conditions, for instance, sea ice concentration is being depleted due to increased warming. They created atmospheric models to study how those factors changed large-scale circulation patterns and pollution over eastern China.

China’s skyline is often characterized by a smoky haze or a smog-filled skyline because that’s just how the air pollution issue has blown up in the country. Dealing with air pollution has been a part of every Chinese’s struggle in their day-to-day life. Of course, we all know how much of the products sold in the world today are made in China. The number of Chinese factories and manufacturing plants operating in the country are likewise factors on how the air pollution issue in China has exploded beyond comprehension.

As of writing, the Chinese government has stepped up its efforts in cleaning the air by closing down factories and power plants to reduce circulating particulate matters. They are hoping the measures they are currently taking will offer relief, especially that even the aviation industry suffers as poor visibility is always a challenge for all airlines flying in and out of China. The health of all the Chinese will deteriorate if this air pollution problem persists, so we are hoping everyone is doing their part in addressing this issue because the government alone can’t solve this mammoth of a problem by itself.

The Phenomenon That Is El Niño

The world is like a box of chocolates. You’ll never know what you get with each passing day. Sounds familiar, right? It is an edited version of a famous line from an equally famous all-time favorite movie. Depending on what part of the world you are in, there are attractions and phenomenon exclusive to that place only. It is the same with weather disturbances. Other nations deal with frequent hurricanes or tornadoes while others have to live with constant movement in the ground a.k.a. earthquake.

It is time to know more about a weather phenomenon that isn’t as talked about as the others but just as savage – El niño. It has its counterpart, La Niña. They both make up the El Niño-Southern Oscillation (ENSO) cycle, the scientific term for temperature fluctuations between the atmosphere and the ocean in the east-central Equatorial Pacific that happens every few years or so. La Niña is known as the cold phase while El Niño is the warm phase. The latter is characterized by warm Pacific waters usually in the month of December and may likewise affect wind shear, which is the blowing of air currents from a lower altitude in a different direction than that of higher winds in the atmosphere.

A weak El Niño pattern will develop in the Pacific, meaning there’s the likelihood of a wetter summer in the Midwest, Commodity Weather Group, the Bethesda, Maryland-based forecaster, said in a seasonal report Tuesday.

The wetter-than-normal weather likely will have a negative effect on planting but a positive impact on crops that get planted due to ample moisture, the forecaster said. The El Niño pattern will mean warmer waters near the Baja Peninsula and relatively cooler waters in the Pacific Northwest.

“The central (and) southwest Midwest is at most risk for slower-than-average corn (and) soy seeding, but rains aid moisture for the heart of the Corn Belt heading into summer,” CWG said in the report. “Summer temperature outlook trended warmer in the eastern U.S., but mostly unchanged in the Corn Belt, keeping the threat for notable Midwest-focused heat low this season.”

The Pacific Northwest should brace for the incoming wet weather later this year because of a weaker El Niño phenomenon. Storms are more likely to form as there is more energy in the warm water during El Niño.

Generally speaking, there is a link between El Ninõ and increased wind shear in the tropical Atlantic Basin. Wind shear limits both the development and strength of tropical cyclones.

This is one of the factors that contributed to the 2017 Atlantic hurricane season outlook issued recently by Colorado State University, which calls for a slightly below average number of named storms and hurricanes.

The most recent El Niño occurred in 2015 and that year the Atlantic hurricane season saw a slightly below-average number of tropical cyclones, with 11 named storms, 4 hurricanes and 2 major hurricanes. The 30-year average is 12 named storms, 6 hurricanes and 2 major hurricanes.

If El Niño develops, parts of the U.S. could see cooler-than-average temperatures later in the summer, according to Dr. Todd Crawford, chief meteorologist with The Weather Company.

Keep in mind that El Niño is only one factor of the atmospheric pattern, but it can play an important role in the weather in the U.S.

Weather changes have a bigger impact in our lives than just having to make up your mind whether to bring an umbrella or not to work or school or whether you should dress up or not when you go outside. The weather is also a big factor when it comes to crop production. It can easily spell a good or bad yield and monetary profits or losses. Others are hoping that the expected El Niño phenomenon this year will be the answered prayer to drought issues in the West Coast but sorry to burst your bubble because it likely won’t have that much positive impact since most of the runoff is headed to sea where people can no longer benefit from it.

Eco-Travel For Your Next Summer Getaway

The sun is up and summer is fast approaching. Many of you can’t probably wait to hit the beach after being cooped up inside your homes during the long, cold and bleak winter months. Not seeing the bright and blinding light of the sun can make people feel down and depressed. So, let us all rejoice with the coming of spring because we know summer is just around the corner and you finally have an excuse to use your vacation credits for a much-needed travel time.

If you are not a fan of crowds, eco-traveling is a welcome reprieve from your busy scheds and modern life. Going the less traveled road can open up your eyes to the beauty of nature. It is likewise less expensive than going to more popular tourist attractions. However, just be prepared to enjoy the entire experience, both the good and the bad. You can’t always expect a comfy and convenient life when traveling this way but you get to immerse with the people and the local culture that can leave you with many wonderful memories you’ll cherish for your lifetime.

As the largest global service industry, tourism can—and should—play a significant role in conservation and environmental sustainability. That was the message that U.N. Secretary-General Ban Ki-Moon delivered on World Tourism Day in 2012. “One of the world’s largest economic sectors, tourism is especially well‐placed to promote environmental sustainability, 'green' growth and our struggle against climate change through its relationship with energy," he said. 

Robert Baden-Powell, founder of the world Scouting movement, was an early proponent of not only treading lightly when you travel, but also doing some good while you're there. In his last message before his death in 1941, Baden-Powell neatly summed up his philosophy: “Leave this world a little better than you found it.” It's a sentiment that anchored the "Leave No Trace" outdoor/camping ethos that took root in the 1960s, and it can easily serve as a motto for ecotourists and ethical travelers alike.

While we all want some well-deserved R&R for all our hard work, it doesn’t mean we can do whatever we want during our dream vacation. We leave our footprints in every place that we visit. Let us always remember to leave no trace especially when communing with nature. Leave the place as it is just like when you got there. Every piece of trash you throw messes up the natural ecosystem and significantly affects the wildlife in a bad way.

Just as the 100th birthday of the National Park Service is casting a spotlight on U.S. national parks in 2016, we can expect an enhanced emphasis on ecotourism throughout 2017—declared the International Year of Sustainable Tourism for Development by the United Nations.

To be sure, the idea of ecotourism isn’t a new one—it’s already known as one of the fastest growing segments in the tourism industry. Put that together with family travel—another of the industry’s rapidly growing segments—and the time is ripe for family vacations that include ecotourism.

At its core, the concept of ecotourism is simple. According to The International Ecotourism Society (TIES), ecotourism is defined as "responsible travel to natural areas that conserves the environment, sustains the well-being of the local people, and involves interpretation and education."

And, as with so many segments of tourism, the line blurs easily, with ecotourism overlapping with adventure travel, wellness travel and voluntourism, to name just a few other popular segments that often go hand-in-hand with ecotourism.

While most people think of eco-travel as a thing for solo travelers or people who don’t have added responsibilities in life like a spouse and kids, you’d be surprised to learn that eco-travel also works for families who love to travel. Family travels should not revolve around trips to theme parks, resorts or cruise ships because developments in ecotourism ensure families, especially the ones with kids in tow, can still have the time of their lives under the bright skies at night without much modern distraction.

Kids actually love nature and active play does a lot of good for their normal growth and development. No kid will ever shy away from playing in the mud or learning more about unknown animals and fauna in some of the nation's popular national parks. It is why eco-travel should be something your family should be doing this summer because the threat of climate change, pollution, and global warming are wreaking havoc on the planet and we may never be able to see some of these species in the years to come. So, the best time to do it is now.
