1.) Thunderstorms are when air masses become unstable and the bottom layer is warm and humid, but the top is cool. Thunderstorms can produce hail, rain, snow, freezing rain, sleet, and tornadoes.

Thunderstorms: Thunderstorms form when an air mass gets so unstable that it overturns violently. The process of a thunderstorm will continue until the heat and humidity will cool down.

1.) Thunderstorms are caused when a cold air mass meets a warm air mass and the cold air mass acts as a bulldozer which pushes the warm air up into the atmosphere then the air condenses and forms a cloud then if it has enough moister it makes rain.

The cause of thunder storms are when an air mass becomes so unstable that it overturns violently. The lowest layers are usually warm, and the top layers are unusually cool.

Thunderstorms are caused by moist air, heated by the sun, rises which causes an updraft of air. As warm air rises, water in the air forms clouds. When water vapor in the cloud gets too heavy, it falls as rain. Conflict between the warm updraft of air and cool water in the clouds causes thunder and lightning. The severity of the thunderstorm depends on the difference in temperature.

Thunderstorms- A thunderstorm forms when warm, moist air in a raincloud rises rapidly. The motion within the cloud makes it unstable, and the temperature outside the cloud falls quickly, which causes a warmer updraft. When the water vapor in the cloud starts to condense into a liquid and that starts to turn into hail, it sort of stokes the fire you could say, which causes turbulence inside the cloud. This triggers the cloud to go off, and it spits out precipitation and lighting in a very violent way.

Thunderstorms are found at the beginning edge of a cold front. They are started when a warm area has a lot of moisture and the cold air front comes in and rings out all the moisture that is in the air at the time. Hail is made by the air blowing ice particles back up into the moisture filled air each time the particle goes back into the air a layer or two wraps itself around the ball of ice then once it gets to heavy it falls out of the sky and hits the ground or cars or houses. Tornadoes are made in a cold front entering a warm front. When a tornado is starting it usually starts horizontally then progresses itself vertically. Almost 95% of tornadoes rotate in a counter-clockwise rotation. Hurricanes are formed when a bunch of rain is already evaporated but when a hurricanes starts it evaporates more and more water particles so it can continue to go on and on. In the middle of the eye this is where calm winds can exist. I think hurricanes. Can cause the most damage because they keep on continuing because the water vapor is just evaporating then it is precipitating over and over again, because it has an endless supply of water.

1. Thunderstorms form when an air mass becomes so unstable that it turns violent. Pockets of near surface air in an unstable air mass expand and cool, as some of the water vapor present condenses into a cloud it releases heat, which then makes the air l even warmer, forcing it to rise still higher in the atmosphere. Thunderstorms are most common in the afternoon over land, when daytime heating of the land by the sun causes the lower part of the troposphere to become unstable from higher temperatures and more water vapor in the air. Or, some thunderstorms can form as result of the upper atmosphere becoming unusually cool, due to the approach of an upper air disturbance. In this case storms can form at any time of day, even when there hasn't been daytime heating of the lower atmosphere over land. There must be a good amount of water vapor in order for the storm to form, since cloud and precipitation originates as water vapor. This is the fuel for the thunderstorm, as the storm uses this fuel, it is converted to rainfall. Eventually, the storm stabilizes the atmosphere by using up the excess water vapor and cooling the lower atmosphere, and warming the upper atmosphere.

Air moves in invisible currents through the lower portion of the atmosphere, known as the troposphere. The temperatures of large masses of air go into a form and create a thunderstorm.
