Annual Averages and Variations
Understanding and predicting such climatic changes are the basic goals of climatology. Climatology is the study of Earth's climate and the factors that cause past, present, and future climatic changes.
- Located between 23.5 degrees north and south of equator.
- Receives the most solar radiation because of the Sun's rays are nearly perpendicular to Earth's surface.
- lies between 23.5 and 66.5 degrees north and south of the equator.
- Moderate temperatures within these regions.
Two of the main causes of weather are the movement and interaction of air masses.
Average weather conditions in and near regions of air-formation are similar to those exhibited by the air masses themselves.
