Weather Forecasting

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

3
Weather Forecasting Tools

• Weather Balloons
• carries electronic
• equipment up to 30 km
• high which measures
• temperature
• air pressure
• relative humidity
• wind speed
• direction
• Transmits radio signals
• to meteorologists

4
Weather Forecasting Tools

• Windsock a cone-shaped cloth bag that is open
  at both ends
• wind enters wide end and exits through narrow
  end
• wide end always points into the wind

5
Weather Forecasting Tools

• Wind Vane shaped like an arrow and attached to
  a pole
• wind pushes the tail of arrow
• vane spins until arrow points into wind

6
Weather Forecasting Tools

• Anemometer 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

7
Weather Forecasting Tools

• Radar used to locate fronts and air masses
• can show how much precipitation is falling and
  what kind it is

8
Weather Forecasting Tools

• Satellites orbits Earth to produce images of
  weather systems
• can also measure wind speeds, humidity, and
  temperatures
• used to track storms

9
Weather Maps

• Weather Maps
• contain a station model a symbol that shows
  the weather at a certain location

10
Weather Maps

• Weather Maps
• contain isobars lines that connect points of
  equal air pressure
• closed circles represent areas of high or low
  pressure

11
Weather Maps

• Weather Maps show
• fronts
• air masses
• high pressure
• low pressure
• temperature
• precipitation

Recap!!!
How is an anemometer different from a windsock or
a wind vane?
Anemometers measure wind speed. Windsocks and
wind vanes are used to find wind direction.
What is a weather balloon and how does it work?
It carries electronic equipment up to 30 km high
and transmits radio signals to meteorologists.
It measures temperature, air pressure, relative
humidity, wind speed direction.

Climate Zones
17
Climate Zones

• There are three climate zones
• Tropical Zones
• Temperate Zones
• Polar Zones

18
Climate Zones

• Tropical Zone known as the Tropics because it
  receives so much solar energy, it has high
  temperatures hottest climate zone
• found between 23.5 N and 23.5 S latitude
• surrounds the equator

19
Climate Zones

• Temperate Zone receives less solar energy than
  the Tropical Zone
• temperatures tend to vary depending on location
  and time of year
• this is the middle zone found between 23.5 and
  66.5 north or south latitudes
• most of the US is in this zone

20
Climate Zones

• Polar Zone is the coldest climate zone
• found between 66.5 and 90 north and south
  latitudes
• extends to the poles
