Cumulus clouds in fair miller & levine biology 2010 on-level chapter 31 pdf. However, systems with significant rainfall and duration help alleviate drought in places they move through.
Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling. When surface temperatures are below freezing, but a thick layer of above-freezing air remains aloft, rain can fall into the freezing layer and freeze upon impact into a glaze of ice. Ice storms also make unheated road surfaces too slick to drive upon. Ice storms can vary in time range from hours to days and can cripple small towns and large urban centers alike. There are varying definitions for blizzards, both over time and by location. Snow storms, especially ones with a high liquid equivalent and breezy conditions, can down tree limbs, cut off power, and paralyze travel over a large region. Usually just referred to as a storm, these systems can sink vessels of all types and sizes.
Firestorms are conflagrations which attain such intensity that they create and sustain their own wind systems. It is most commonly a natural phenomenon, created during some of the largest bushfires, forest fires, and wildfires. Wind storm— A storm marked by high wind with little or no precipitation. Windstorm damage often opens the door for massive amounts of water and debris to cause further damage to a structure. These storms occur when high levels of condensation form in a volume of unstable air that generates deep, rapid, upward motion in the atmosphere.
Cool descending air currents produce strong downdraughts below the storm. After the storm has spent its energy, the rising currents die away and downdraughts break up the cloud. Hailstorms usually occur during regular thunder storms. A tornado is a violent, destructive wind storm occurring on land. Usually its appearance is that of a dark, funnel-shaped cloud.
Storms can last anywhere from 12 to 200 hours, depending on season and geography. In North America, the east and northeast storms are noted for the most frequent repeatability and duration, especially during the cold period. They tend to occur when Mars comes closest to the Sun, and have been shown to increase the global temperature. One particularly large Martian storm was exhaustively studied up close due to coincidental timing. The surface of the planet was totally obscured.
