Hurricanes Ingredients:
- warm tropical water
- at least 80° F
- high humidity
- light wind
- low pressure area
- form between 5° and 20° latitude
Hurricanes weaken as they move over land
- they lose their source of heat and moisture
- friction over land also reduces the circulation of surface winds, weakening a hurricane
Monsoons
- Monsoons blow from the land toward the sea in winter, and from the sea toward land in the summer
- Runs from June to September
- Intense period of heavy rain, booming thunder, and plenty of lightning
El Nino
- abnormally high surface ocean temperatures off the coast of South America
- causes unusual weather patterns across the globe
- occur every 2 to 7 years
- Starts because the easterly trade winds weaken and allow the warm waters in the Western Pacific to move east toward South America
- changes where the convection current occurs causes rain where it usually doesn't occur and drought where it usually rains
La Nina
- After the El Nino phase, the La Nina follows abnormally
- Low surface ocean temperatures off the coast of South America causes unusual weather patterns across the globe
