Meteorology

Wait??? … that is not right!

Much better. Meteorology

Meteorology is the study of atmospheric phenomena. The word meteor means (high in the air).

Types of meteors Hydrometeors – Clouds that contain water (water)(high in the air) Lithometeors – Smoke, haze, dust, and condensation nuclei (rock)(high in the air) Electrometeors- Thunder and Lightning visible or audible electricity (Electricity)(high in the air)

Weather Weather is the current state of the atmosphere, including short-term variations that affect our lives. Ex. It is sunny today, it will rain tomorrow.

Climate Climate describes the average weather over a long period of time and is usually averaged over the course of 30 years or more.

A Question of Balance In meteorology, a crucial question is how solar radiation is distributed around the planet.

Air Masses An air mass is a large body of air that takes on the characteristics of the area over which it forms. Air masses that form over land are generally drier than those that form over water.

Air Masses Classifying Air Masses –Air masses are classified according to their source regions. –The main types of air masses are: warm and dry continental tropical (cT) warm and humid maritime tropical (mT) cold and dry continental polar (cP) cold and humid maritime polar (mP) arctic (A)

Air mass modification is the exchange of heat or moisture with the surface over which an air mass travels.
