- Length of Day -
Length of day is longer, even in Winter: least 10 hours of sunlight.

How is insolation unique here?

Orlando, Florida is located near the equator. So, the amount of solar radiation energy transferred is larger than any other states in U.S.

Unique features of the water cycle

Orlando has flat surfaces, so not much of water goes back to ocean directly. Most of water are stored in many lakes.
Large amount of sunlight makes them evaporate rapidly.

Would this area experience dew?

Why?

• On a clear night, the temperature decreases rapidly.
• Because of the decreased temperature,
• clouds cannot hold more of water vapours.
• When sun rises, those water vapours condense.
• Condensed water vapour is dew.

Would this area experience fog?

Why?

• Every morning, warmer air from Gulf Stream
• heats up the cooler ground air.
• It reaches to its due point and creates fog.

Would this be a cloudy region?

Types of Clouds
- Cumulonimbus and Cumulus: sun heats up the surface and the air repeats rising and falling.

Common types of rainfall.

Why?

• The sun heats up the surface. (flat land)
• Warmed air forced to rise.
• Air cools as it rises and condenses.
• It releases large amounts of water.

Jet Stream
- Occasionally, low pressure dragged by jet stream cools the land of Florida, so many of tropical fruits freeze.
