Oct. 20 Bell Ringer What atmosphere level is cooler in the lower levels and warmer in the higher levels? Jet planes fly here. A. Exosphere B. Troposphere C. Stratosphere D. Thermosphere

Global and Local Winds https://www.youtube.com/watch?v=uBqohRu2RRk SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Air Movement   SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Wind is the movement of air caused by differences in air pressure Wind ALWAYS moves from areas of high air pressure to areas of low air pressure. The greater the difference, the faster the wind moves

Differences in air pressure are caused by the uneven heating of Earth SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Differences in air pressure are caused by the uneven heating of Earth Uneven heating produces pressure belts which occur every 30° latitude

As warm air rises at the equator and moves toward the poles, it cools Pressure Belts  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. As warm air rises at the equator and moves toward the poles, it cools As it cools, some of the air sinks around 30° north and south of the equator

At the poles, cold air sinks and moves towards the equator Pressure Belts  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. At the poles, cold air sinks and moves towards the equator Around 60° north and south, the air begins to heat up and rise

These are polar easterlies, westerlies, and trade winds Global Winds  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. The combination of pressure belts and the rotation of the Earth cause global winds These are polar easterlies, westerlies, and trade winds

Wind belts that extend from the poles to 60° latitude Polar Easterlies  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Wind belts that extend from the poles to 60° latitude Formed from cold sinking air moving from the poles creating cold temperatures

Exit Ticket  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather Answer these 3 questions on the exit ticket sticky: 1. What causes the global winds? 2. What is a pressure belt? 3. What are the polar easterlies?

Wind belts found between 30° and 60° latitude Westerlies SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Wind belts found between 30° and 60° latitude Flow towards the poles from west to east carrying moist air over the Unites States

Winds that blow from 30° almost to the equator Trade Winds SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Winds that blow from 30° almost to the equator Called the trade winds because of their use by early sailors

Doldrums SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Located along the equator where no winds blow because the warm rising air creates an area of low pressure

Most deserts on the Earth are located here because of the dry air Horse Latitudes SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Occur at about 30° north and south of the equator where the winds are very weak Most deserts on the Earth are located here because of the dry air

Separates warm air from cold air Jet Stream SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. The jet streams are narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere Separates warm air from cold air

Generally move short distances and can blow in any direction Local Winds SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Generally move short distances and can blow in any direction Caused by geographic features that produce temperature differences

Air moves from the ocean to the land creating a sea breeze Sea Breezes SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. High pressure is created over the ocean during the day and low pressure over land due to uneven heating Air moves from the ocean to the land creating a sea breeze

Land Breezes SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Low pressure occurs over the ocean during the night and high pressure over land due to the uneven heating of earth This causes wind to move from the land to the ocean creating a land breeze

Question 1SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. What causes winds?

Answer SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Winds are caused by the uneven heating of Earth’s surface, which causes pressure differences

What are the three types of global winds? Question 2 SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. What are the three types of global winds?

Polar Easterlies Westerlies Trade Winds Answer SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Polar Easterlies Westerlies Trade Winds

What is the difference between a land breeze and a sea breeze? Question 3  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. What is the difference between a land breeze and a sea breeze?

Answer SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Sea breezes occur during the day when the land is warmer than water and a land breeze occurs at night when the water is warmer than land
