Natural Disasters: Droughts, Floods, and Tornadoes How they affect the climate Scott Plank, Maxx Gunn, and Billy Beefer
Droughts • A drought is an extended period of months or years when a region notes a deficiency in its water supply • Droughts cause drastic problems within an area that has been affected. • Already dry areas are more apt for a draught.
How do droughts affect climate? • Droughts cause migration and relocation of people and animals. • The climate will be cleaner due to the lack of humans burning fossil fuels • Draughts can also cause the land to get so dry that wildfires occur. • Wildfires can cause the temperature of the climate to increase or decrease.
Floods • The rising of a body of water and overflowing onto normally dry land • Floods can severely transform a pre existing area of land. • Coastal areas are more apt to have a flood.
How do floods affect climate? • Floods can wipe out stores, businesses, homes which is bad for everyone. • The climate is affected because there is a lot of excess water vapor in the atmosphere and on Earth’s surface.. • Floods usually come after a lot of rain.
Tornadoes A tornado is a violent, dangerous, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes come in many sizes but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust.
Tornadoes This video shows that tornadoes are extremely powerful and are a force to be reckoned with.
How the climate affects tornadoes! • During a tornado, there is a lot of precipitation including hail, rain, and sometimes sleet. • When warm, moist air hits eastward moving cold fronts, thunderstorms start developing a dry line which keeps warm air to the east from dry air in the west.
Tornado Variations • Water Spouts- weak tornadoes that form over water • - are most common along the gulf coast and southeastern states • Transparent Tornado- tornado that is “invisible” but the presence of wind is there and you can only see it once debris, dust and wind pick up.
