Wind Lesson 5.5. What causes Wind? Differences in air pressure are caused by unequal heating of the atmosphere – Discovery lab – What warms up faster?

Warm air near the Earth’s surface rises and then cools as it goes back up. Convection happens on a global scale in the atmosphere and causes global winds,

Winds What causes winds?.

The unequal heating of the Earth's Atmosphere and Surface CAUSES Changes in air pressure WHICH CAUSES WIND.

Convection Currents  An area of Earth’s surface is heated by the sun’s rays.  Air over heated surface expands and becomes less dense and the air pressure.

Local Winds EQ: What are local winds?. STOP & THINK Think about notes on Convection Currents… – Convection Currents are the constant circulation of warm.

Oct. 21 Bell Ringer What do you believe causes winds? SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather. Winds Oct. 21 Bell Ringer What do you believe causes winds?

Winds are caused by differences in air pressure. They move from areas of high pressure to low pressure. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Differences in air pressure are caused by unequal heating of the atmosphere. Cool air has higher air pressure so it flows underneath the warm, less dense air. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Measuring Wind direction A wind vane measures wind direction. The name tells where the wind is coming from. i.e. – north wind blows from the north to the south. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Wind speed An anemometer measures wind speed. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Wind-chill factor The wind-chill factor is the increased cooling that a wind can bring. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Local Winds Winds that blow over short distances and are caused by unequal heating of Earth’s surface within a small area. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Sea Breeze – a wind that blows from an ocean or lake onto land Sea Breeze – a wind that blows from an ocean or lake onto land. Land Breeze – the flow of air from land to a body of water. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.

Monsoons Sea and land breezes over a large region that change direction with the season. SPI 0607.8.1 Analyze data to identify events associated with heat convection in the atmosphere. SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.
