Meteorology Layers of the Atmosphere
Meteorology § Meteorology is …
Meteorology § Meteorology is the branch of science that deals with the atmosphere of a planet, particularly that of the Earth, the most important application of which is the analysis and prediction of weather.
Kid definition § Meteorology is the study of the atmosphere to analyze and predict the weather.
Background Info § Although the density of air decreases with the increasing altitude, that is, the air gets “thinner”, the proportions of gases in the air remain relatively the same, at least in the lower layers. Water vapor is found in the atmosphere, but its concentration varies with weather and climate conditions. For example, air is generally dry over the southwestern states but relatively wet over the southeastern region, which includes the Florida Keys. § Top Ten Gases in Our Atmosphere

Ozone is a form of oxygen found in the atmosphere. The _ozone_layer_ protects Earth’s living things from ultraviolet radiation_ from sun. Some say there is a hole in our ozone layer. It is not exactly a hole but a thinning of the ozone layer where it is in low concentrations. Felix Baumgartner's fall from space

Atmospheric Circulation § Atmospheric circulation on planets
Global Winds Little Shop of Science - global circulation § Global winds are the result of uneven heating. The air over the equator is warmer than the air over the poles. As a result, the hot air over the equator rises, and the cold air from the poles slips in under it. Global winds are curved by the Earth’s rotation. The direction of the earth’s rotation and its wind patterns is shown.
The Coriolis Effect § The rotation of the Earth causes and interesting phenomena on free-moving objects on Earth. Objects in the Northern Hemisphere are deflected to the right while objects in the Southern Hemisphere are deflected to the left. § Will a toilet flush opposite in Australia?
Jet Stream § How does our jet stream work?
High and Low Pressure high and low pressure convection clip § The air’s density can help you predict the weather. Scientists determine how many particles are in the air by measuring how heavy the air is. Air with more particles in it is heavier than air with less particles. The weight of this air is always pushing on us and is known as air pressure. Since cold air is more dense than warm air it is heavier and greater air pressure and forms high pressure areas. Warm air is less dense and forms low pressure areas.
