What are winds? How are winds formed? What are winds? A 'wind' is simply the flow of a huge amount of air, usually from a high pressure-area to a low-pressure area. How are winds formed? Typically, this begins with the sun’s radiation, which is absorbed differently on the earth’s surface. As a result of this uneven heating, there are bound to be earth surfaces that vary a lot in temperature. Important: Hot air rises and cool air sinks. Let us see this illustration below showing pressure and wind direction: In the diagram above, notice how cool air falls, resulting in high pressure, and moving towards regions of low pressure. Anywhere and each time there are differences in atmospheric (air) pressure, there will be a wind, because air will move from the high-pressure area to the low-pressure area. A good example is how tropical depression forms, where warm air over hot tropical waters rise, and high-pressure cold air quickly rushing to fill the space. Did you know?
What Are Hurricanes, and How Do They Form? Every year, coastal regions brace themselves for violent windstorms known as hurricanes. But how do these storms form and grow? The oversimplified answer: Warm ocean water plus the Earth’s eastward rotation. “They’re heat engines,” said meteorologist Jeff Masters of the website Weather Underground in a previous interview. “They take heat from the oceans and convert it to the energy of their winds. They’re taking thermal energy and making mechanical energy out of it.” The natural engine that is a hurricane is fueled by warm, moist air. According to NOAA’s National Hurricane Center, the average hurricane eye—the still center where pressure is lowest and air temperature is highest—stretches 20 to 30 miles across, with some even growing as large as 120 miles wide. The strongest storms, equivalent to Category 5 on the Saffir-Simpson scale, have sustained winds that exceed 155 miles an hour. Why Are Hurricanes Dangerous? It’s the number one killer in hurricanes, Emanuel explained.

Weather Wiz Kids weather information for kids Wind What is wind? Wind is air in motion. It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. What causes the wind to blow? What is a windstorm? What is a gust front? What is a downburst? What is a monsoon? What are the trade winds? What are the polar easterlies? What is a land breeze? How is wind helpful to Earth? What are some different types of wind names? Beaufort Scale The Beaufort scale is an empirical measure for the intensity of the weather based mainly on wind power.

Hurricanes take their toll on US jobs market Image copyright Getty Images US employment fell in September for the first time since 2010 as hurricanes Harvey and Irma took their toll on the jobs market. The Labor Department said 33,000 jobs were lost amid a record drop in employment in the leisure and hospitality sector. It blamed the two storms, which struck Texas and Florida in late August and early September, for the slide. Economists had expected a rise of 90,000 jobs last month. However, Harvey and Irma did not affect the unemployment rate, which slipped to 4.2% - the lowest since February 2001. The US Labor Department uses separate surveys to capture payrolls data and the unemployment rate. Economists said the discrepancy between the two September reports suggests the jobs decline does not indicate a long-term trend. Gus Faucher, chief economist at PNC Financial Services said: "Although the headline number for September is loss of jobs, the first in seven years, the labour market remains in good shape."
Weather Wiz Kids weather information for kids Winter StormsHow do winter storms form?Winter storms derive their energy from the clash of two air masses of different temperatures and moisture levels. Winter storms usually form when an air mass of cold, dry, Canadian air moves south and interacts with a warm, moist air mass moving north from the Gulf of Mexico. The point where these two air masses meet is called a front. If cold air advances and pushes away the warm air, it forms a cold front. How is snow formed? How do blizzards form? What are snowflakes?

Stronger storms mean new 'category six' scale may be needed | Environment The increasing strength, intensity and duration of tropical cyclones has climate scientists questioning whether a new classification needs to be created: a category-six storm. The Saffir-Simpson hurricane wind scale currently runs in severity from one to five, with five describing near-total destruction. But climate scientists meeting at a conference in the New Zealand city of Wellington have floated the idea of creating a category six to reflect the increasing severity of tropical cyclones in the wake of warming sea temperatures and climate change. Climatologist Michael Mann, the director of the Earth system science center at Penn State University said the current scale could be viewed as increasingly outdated. “Scientifically, [six] would be a better description of the strength of 200mph (320km/h) storms, and it would also better communicate the well-established finding now that climate change is making the strongest storms even stronger,” he said. … we have a small favour to ask.
What Causes a Blizzard? Heavy snow, bitter cold, whipping winds … Winter storms are no picnic, but what is the official definition of a blizzard, and what causes them, anyway? The National Weather Service defines a blizzard as any severe snowstorm that is accompanied by strong winds — at least 35 mph — resulting in low visibility. The defining factor of a blizzard is actually the strength of the wind, rather than the amount of snow. While blizzards often feature extreme cold and heavy snow, there are actually no temperature or snow depth requirements for a storm to qualify as a blizzard. Blizzards can be very dangerous. In the United States and Canada, the areas most prone to blizzards are the plains states and provinces, the Great Lakes region, and the Northeastern U.S. and Canadian Maritimes. The Great Lakes region is especially lucky, because it is positioned to be hit by both types of storms.
Japan hit by deadly earthquake and mudslides Image copyright EPA/Jiji press Japan's northern island of Hokkaido has been hit by a powerful earthquake, triggering landslides that engulfed houses. Two people had been killed and about 40 were missing, public broadcaster NHK said. The 6.7 magnitude quake cut power to around 3 million homes and shut down a nuclear plant in the region The earthquake comes on the heels of a deadly typhoon lashing the west of Japan over the past few days. The tremor struck 62km (39 miles) south-east of the regional capital Sapporo in the early hours of the morning. It posed no tsunami risk, the country's meteorological agency said. Image copyright Alamy Image copyright Kyodo/via Reuters Could an emoji save your life during an earthquake? Local residents and travellers in the region have shared their shock about the quake on social media. They also write about long lines at food stores as people stock up on supplies amid fears of more tremors. Image Copyright @j_burza @j_burza Image copyright EPA/Jiji Press
Subjects - Extreme Weather No matter where you live in the world, weather is something that you are exposed to every single day. Even though weather occurs all around the world, the region you live in can have a different natural phenomenon than another geographical locations. For example, if you live in the Midwest of the United States, it isn't very likely that you'll get hurricanes but you may be very familiar with tornados. Why is it sunny most of the year in some places and rainy in other places? What causes tsunamis and earthquakes? Even though weather is different all around the world, our weather systems are all very interconnected.
*****Are hurricanes getting worse? As Florence barrels toward the US east coast, two more hurricanes follow closely behind. The 2018 hurricane season has suddenly erupted, a year after the 2017 season ruined thousands of lives. While 2018 was expected to be “below normal”, there is a great deal of uncertainty. We won’t know the full scale of the damage until the season is over, but longer term trends indicate a worsening of the length and intensity of Atlantic storms. Since 1970, there has been an average of six Atlantic hurricanes per year. What is a hurricane? A hurricane is a large rotating storm that forms over tropical or subtropical waters, though they’re only given such a name if formed in the Atlantic or eastern Pacific oceans. Hurricanes fall into one of five tiers based on wind speed – known as categories – measured by the Saffir-Simpson scale. Hurricanes can be deadly. Are they getting worse? Category 5 hurricanes are the most severe but also the most rare – there have been just three in the past decade.
