- 3. What helps Meteorologists Predict the weather? • Computers • Satellites • Climatology • Trends (study patterns of weather from previous days or even years) • Weather can be predicted up to about 5 days and after that it is more of a guess due to all the different atmospheric pressures that change and bring different weather
- 4. Air Pressure Symbols • High and Low Pressure Systems • A blue "H" means a center of high pressure (usually calm, sunny weather). • A red "L" means low pressure (which can mean storminess). Most fronts extend from low-pressure centers.
- 5. Cloud Cover Symbols • If the circle is empty the skies are clear. • The circle is white if it’s cloudy. • A line within the circle or a half-filled circle means "partly cloudy."
- 7. Forecasting Maps What do you look for? • Look at all the symbols on the map and determine the weather pattern associated with them. • Look at the directions of the fronts moving through an area. • Try to determine whether there is low pressure or high pressure in the area. • Now, put them all together and determine the weather!
