3 Wind is always named by where it is coming from! It is called a NORTH wind because it is moving from the north to the south. What would a wind be named if it is blowing from Georgia to Florida?

5 Most often noticed at the beach!

6 1.Land heats up faster than water. 2.Warm air over land rises. 3.Air over water moves to shore. 4.Would occur during the day. 5.Named a SEA breeze because it comes from the sea.

7 1.Land cools off faster than water. 2.Warm air over water rises. 3.Cool air from land takes its place. 4.Would occur at night. 5.Called a LAND breeze because the wind is coming from the land.

8 Look at these two diagrams. Can you tell which is the land breeze and which is the sea breeze?

9 1. Blow steadily from the same direction all the time. 2. The path is curved because of the Coriolis Effect.

10 Jet Stream 1.In the upper troposphere. 2.Very fast kmh 3.Go completely around the earth.

11 Notice that the jet stream does not stay the same every day. But it is always there!

13 Notice on this weather map in motion how the rain moves toward the east over time.

14 Is a measure of how much water vapor is in the air. It is measured in a percent using a psychrometer. More humidity means more clouds and more likely chance of precipitation.

15 This forms clouds!

16 Clouds from when the water vapor reaches the dew point. Remember that as you go up in the troposphere, the temperature decreases. Dew point

17 If the dew point temperature is the same as the air temperature on the ground, fog forms!

18 Any form of H 2 O that falls from clouds and reaches the earth's surface.

19 The term rain is restricted to drops of water that fall from a cloud and have a diameter of at least 0.5 millimeter. Drizzle and mist have smaller droplets. The most common form of precipitation is rain.

20 Drizzle droplet Mist droplet Cloud droplet

21 As water vapor collects into larger and larger droplets, gravity will cause them to fall to the ground as rain, sleet, hail, or snow.

22 In some places around the world, mountains are so high that rain falls only on one side of the mountains.

23

24 Form when water vapor condenses to form drops of liquid water or ice crystals. There are three main types of clouds.

25 Cirrus – high, thin, feathery clouds Made of ice crystals

26 Cumulus – round, puffy clouds Indicate fair weather

27 Stratus – flat layer of clouds. Often have rain.

28 Cumulonimbus clouds often produce bad weather (lightning and hail) Nimbus means rain. Notice that it is getting flat on the top. That means the top of the cloud has reached the top of the troposphere and cannot go any higher.
