Weather Forecasting Weather Forecast – a prediction of weather conditions over the next few days. Meteorologists use special instruments to collect data for weather forecasting

Weather Balloon carries electronic equipment up to 30 km high which measures: a) temperature b) air pressure c) relative humidity d) wind speed e) wind direction Transmits radio signals to meteorologists.

Wind Sock a cone-shaped cloth bag that determines wind direction. It is open at both ends. Wind enters the wide end and exits through the narrow end. Wide end always points into the wind.

a tool shaped like an arrow and attached to a pole that determines wind direction. wind pushes the tail of arrow. vane spins until arrow points into the wind. Wind Vanes

A tool that measures wind speed Has three or four cups connected to a pole with spokes. Wind pushes on open side of cups and makes them spin. This spinning produces an electric current which is displayed on a dial. Anemometer

Used to locate fronts and air masses Can also show how much precipitation is falling and what kind it is. RADAR

Orbits Earth to produce images of weather systems Can also measure wind speeds, humidity, and temperatures Used to track storms Satellites

Weather Maps Weather Maps Contain: 1.) Station models – a symbol that shows the weather at a certain location

Weather Maps Weather Maps Contain: 2.) Isobars – lines that connect points of equal air pressure Closed circles represent areas of high or low pressure.

Weather Maps Weather Maps show: 1.Fronts 2.Air masses 3.High pressure 4.Low pressure 5.Temperature 6.Precipitation

Recap!!! What is a prediction of weather conditions over the next few days? Weather Forecast What carries electronic equipment up to 30 km high to measure different aspects of weather? Weather Balloon What are 5 things that a weather balloon measures? Temperature, Air Pressure, Relative Humidity, Wind Speed & Direction

Recap!!! What is a cone-shaped sock with openings at both ends that determines wind direction? Wind Sock What is a tool shaped like an arrow and attached to a pole that determines wind direction? Wind Vane What is a tool that measures wind speed and has three or four cups connected to a pole? with spokes? Anemometer

Recap!!! What are 3 things radar can measure? Fronts, Air Masses, Precipitation What orbits Earth to produce images of weather systems? Satellites What are satellites used to measure? wind speeds, humidity, temperatures, storms

Recap!!! What 2 things do weather maps contain? Station Models and Isobars What 6 things do weather maps show? Fronts, Air masses, High pressure, Low pressure, Temperature, Precipitation

What does each symbol stand for? Cold Front Isobar High Pressure Warm Front Low Pressure Stationary Front

Climate Zones There are three climate zones: 1) Tropical Zones 2) Temperate Zones 3) Polar Zones

Key Facts: Known as the Tropics Receives so much solar energy Surrounds the equator Temperature: Extremely high temperatures The hottest climate zone Location: Extends to the equator Between 23.5 N and 23.5 S latitude Tropical Zone

Key Facts: Receives less solar energy than Tropical Zone Most of the US is in this zone Temperature: Vary depending on location and time of year Not as hot as Tropics & not as cold as Polar Location: Middle Zone (Between Tropical & Polar) Between 23.5 and 66.5 North and South latitudes. Temperate Zone

Key Facts: Surrounds the Poles Receives least amount of solar energy Temperature: Extremely cold Coldest climate zone Location: Extends to Poles Between 66.5 and 90 North & South Latitudes Polar Zone

Climate Zone Diagram Equator Polar Zone Temperate Zone Tropical Zone

Recap!!! What are the three climate zones? Tropical Zone, Temperate Zone, & Polar Zone Which zone surrounds the equator? Tropical Zone Which zone extends to the poles? Polar Zone Which zone has temperatures that vary? Temperate Zone

Which zone is the coldest climate zone? Recap!!! Polar Zone Which zone is the hottest climate zone? Tropical Zone Which climate zone is most of the US located in? Temperate Zone

Label the climate zones Polar Zone Temperate Zone Tropical Zone
