3: Wind is caused by differences in atmospheric pressure.. Wind belts are divided into five zones. 1. Doldrums- A doldrums is an area of calm weather that receives the most heat from the sun. 2. Trade Winds- They are air movements toward the equator. Trade Winds are warm, steady breezes that appear to be curving to the west. 3. Horse Latitudes- Horse Latitudes have bright and clear weather that forms from air flowing toward the poles then becoming warmer as it falls to Earth. 4. Prevailing Winds- They are located between 30 and 60 degrees latitude. Prevailing Winds are named from the direction which they originate. 5. Polar Easterlies- Located 60 degrees latitude, Polar Easterlies join with the Prevailing Westerlies to reduce upward motion. They also form when the poles atmospheres cool.
4: An air mass is a large body of air that has similar temperatures and moisture properties throughout.
5: Different types of air masses. cP- continental polar cT- continental tropical mP- maritime polar mT- maritime tropical | A boundary that separates two large air masses is called a front. | Air masses and fronts are related because fronts separate air masses and they both have to do with weather formations.
6: Cumulonimbus Cloud
7: A cumulonimbus cloud is a thunderstorm cloud that forms as cumulus clouds then continue to grow vertically. | Lightning, thunder and violent tornadoes are associated with the cumulonimbus clouds. | Cumulonimbus clouds can have an anvil- like shape.. The anvil usually points in the direction the storm is moving.
8: Cirrus Clouds | Cirrus clouds are white, thin, and high. They can occur as patches or as delicate veil like sheets or extended wispy fibers that often have a feathery appearance.
9: Cirrus clouds are the most common high clouds. Weather associated with cirrus clouds is generally fair to pleasant. | Cirrus clouds often mean that you will see a change in weather in about 24 hours.
10: Cumulus Clouds
11: Cumulus clouds consist of rounded individual cloud masses. | Normally they have a flat base and the appearance of rising domes or towers. Usually described as having a cauliflower structure.. | Cumulus clouds are generally called "fair-weather clouds". If these clouds were to grow upwards the would develop into giant cumulonimbus clouds.
12: Stratocumulus clouds are low, puffy, and gray. When they develop a scalloped bottom appears on stratus clouds. They appear as long parallel rolls or broken rounded patches. | Stratocumulus clouds form in rows where blue sky is visible. Rain is rarely associated with these clouds but they can turn into nimbostratus clouds.

14: Stratus Clouds
15: Stratus clouds are grayish uniform clouds that cover the entire sky.. | Stratus clouds almost look like fog that doesn't touch the ground. | The weather that is associated with stratus clouds is light mist or drizzle.
16: Cirrostratus Clouds
17: Cirrostratus clouds are often thin, white, and made up of ice crystals in flat layers. They are made up of ice crystals because at high altitudes there are low temperatures and small amounts of water vapor. | These clouds are so thin that the sun and moon can be seen through them. You will often see these clouds 12-24 hours before a rain or snow storm.
18: Altostratus clouds are gray or blue-gray clouds composed of ice crystals and water droplets. They cover the whole sky. | Altostratus clouds are the clouds that form ahead of storms with continuous rain or snow. | In some lighter spots of the cloud the sun is visible as a bright spot.
