Weather Forecasting

1. Additional inputs relative to weather changes By: DR. ADRIANO R. MELENDRES, JR.

2. If it CHANGES , then new weather is on the way: Falling Air Pressure = stormy weather is coming Rising Air Pressure = fair weather is coming Steady Air Pressure = no change is coming Moves from areas of HIGH to LOW pressure The greater difference in pressure, the FASTER the wind blows How does Air Pressure affect weather?

3. Caused by the temperature difference in different regions Hot Tropical Regions—causes air to rise Cold polar Regions—causes air to sink Affected by Earth’s Spin Coriolis Effect = causes winds to curve to the right in the N. Hemisphere; to the left in the S. Hemisphere Global Winds

4. How does the Ocean affect weather? Ocean currents will affect the temperature of the land they pass by ; Cold ocean currents = cooling effect Warm ocean currents = warming effect Temperature changes affect air pressure – which then creates WINDS Winds blow this cooling or warming effect over the land

5. CLIMATE CHANGE SIGNS Tornado: clouds, strong wind, rain, hail Hurricane or cyclone: strong wind, heavy rain Blizzard: heavy snow, ice, cold temperatures Dust storm: strong winds, arid conditions Flood: heavy rainfall Hail storm: cold or warm temperatures, rain, ice Ice storm: freezing rain Erratic occurrence of:
