Weather Types

FOG Fog forms when cool air passes over a warm body of water or moist land. In general we see that fog is formed whenever there is a temperature difference between the ground and the air. When the humidity is high enough and there is enough water vapor or moisture fog is sure to form.Sources: http://en.wikipedia.org/wiki/Tule_foghttps://www.google.com/webhp?sourceid=chrome-instant'ion=1'espv=2'ie=UTF-8#q=how%20does%20fog%20from

THUNDERSTORMS Thunderstorms form when The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.

LIGHTNING Lightning forms within a thundercloud. Many small bits of ice bump into each other as they swirl around in the air. After a while, the whole cloud fills up with electrical charges. The ground's electrical charge concentrates around anything that sticks up. The charge streaming up from these points eventually connects with a charge reaching down from the clouds, and lightning strikes.Source:http://www.ucar.edu/communications/infopack/lightning/kids.html http://www.thesaint-online.com/2014/05/research-shows-lightning-may-have-contributed-to-creation-of-life/

HURRICANESHurricanes form over warm ocean waters. The air must cool off quickly and the wind must be blowing in the same direction, and at the same seed to force the air upward from the ocean surface. Winds flow outward above the storm allowing the air below to rise. The Coriolis Force is needed to create the spin in the hurricane.

TORNADOA tornado is formed when air rotates because of wind shear. The faster spin causes a funnel cloud to form. Then the funnel rotates and touches down. Sources:http://www.eo.ucar.edu/kids/dangerwx/tornado3.htm http://whyfiles.org/2014/tornadoes-strike-again-how-do-they-work/

Mammatus CloudsThese odd-shaped clouds are often associated with a storm front, especially one involving a thunderstorm. It’s not completely understood how they form. Source: http://listverse.com/2008/04/19/20-amazing-and-unusual-weather-phenomena/

BLIZZARDBlizzards form when clouds get cold enough that the precipitation forms snow. Then the blizzard happens when there are a lot of clouds and precipitation(in the form of snow). The temperature also has to be cold enough on the ground. Sources: http://www.englishexercises.org/makeagame/viewgame.asp?id=7192 https://eo.ucar.edu/kids/dangerwx/blizzard3.htm

HAIL Hail forms when strong currents of rising air, known as updrafts, carry water droplets high enough in a thunderstorm for the water droplets to freeze.Sources:http://www.cocorahs.org/Content.aspx?page=hail http://usatoday30.usatoday.com/weather/tg/whail/whail.htm

HOLE PUNCH CLOUDS Clouds are made of water droplets, and hole punch clouds—also known as fallstreak hole clouds—occur when part of that cloud falls out, leaving behind a hole. That opening in the cloud is the result of an extremely localized snowfall. Source:http://news.nationalgeographic.com/news/2014/11/141104-hole-punch-cloud-rainbow-atmosphere/

WATERSPOUTSThe water inside a waterspout is formed by condensation in the cloud. There are two major types of waterspouts: tornadic waterspouts and fair-weather waterspouts.
