- The data used to describe an area’s climate include daily high and low temperatures, amounts of rainfall, wind speed and direction, humidity, and air pressure.
- The data are averaged on a monthly or annual basis for a period of at least 30 years to determine the normals, which are the standard values for a location.
Limitations of Normals
- When climatic normals are based on airports Data, they might differ from actual weather conditions in nearby cities.
- Great effect on climate, and the amount of solar radiation received on Earth decreases from the equator to the poles.
- The area between 23.5° S and 23.5° N of the equator is known as the tropics.
- temperate zones lie between 23.5° and 66.5° north and south of the equator.
- Water heats up and cools down more slowly than land. Thus, large bodies of water affect the climates of coastal areas.
- Orographic lifting leads to rain on the windward side of a mountain. The leeward side is usually dry and warm.
