Dangerous Weather On a hot summer day the surface of the Earth is heated by the sun. The Earth's surface heats the air just above the surface through the process of conduction. The action of warm air rising and cold air sinking (convection) plays a key role in the formation of severe thunderstorms. If the warm surface air is forced to rise, it will continue to rise, because it is less dense than the surrounding air. In addition, it will transfer heat from the land surface to upper levels of the atmosphere through the process of convection. Two of the most important ingredients for thunderstorm formation are instability (unstable air) and moisture. There are three main types of thunderstorms; orographic, air mass, and frontal. Supercell thunderstorms occur when very strong updrafts are balanced by downdrafts. The result is a strong, persistent updraft of warm moist air. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.

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.

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?
