I believe there are only 5 different air masses in the US:
1. Arctic Polar
2. Continental Polar
3. Maritime Polar
4. Continental Tropical
5. Maritime Tropical
Hope this helped!
Jet streams are caused by a combination of Earth's rotation on its axis and atmospheric heating by solar radiation. The Coriolis effect describes how a planet's surface and atmosphere rotate fastest relative to each other at the planet's equator while virtually not rotating at all at the poles. While this speed difference generally has very little effect on Earth's surface, it plays an important role in atmospheric air currents because air at higher levels of the atmosphere, especially near the equator, must travel very fast to keep up with the planet's rotation. Thus there is a tendency for air at higher levels of the atmosphere to "slip" and fall behind the speed of the air below. This results in a pressure buildup behind the "slipped" air, and so some air will have to catch up by moving in the same general direction as the planet's rotation (west to east on Earth); however, this air does not follow a simple pattern but instead is also influenced by its temperature and water content compared to that of surrounding air regions. In essence, instead of the atmosphere moving along with the planet consistently, parts of the atmosphere travel faster than others via jet streams. Jet streams form near boundaries of adjacent air masses with significant differences in temperature, such as the polar region and the warmer air towards the equator.
There are 6 major factors that help to determine weather. They are air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.
When the Earth surface is heated by the sun, the AIR above the surface is also warm. The warm air rises, and when it rises it cools down. Then it condenses and form clouds. And then it rains. (If the air rises very quickly cumulonimbus clouds can form) So the simple answer, Convectional Rainfall: Water forces to rise by heat.
Fronts are associated with cyclones, or areas of low pressure, and occur when cold air masses meet warm ones (1). The circulation of the Earth's atmosphere causes the cold air to move eastwards and equatorwards (2) and the warm air to move eastwards and polewards in a wedge shape called the warm sector (3). This movement causes the front to buckle (4), with a warm front to the east, where the leading edge of the warm sector is replacing cold air, and a cold front to the west (5). Because cold air moves faster than warm air, the warm sector is gradually squeezed and the front occludes and decays (6).
The troposphere is the layer of the atmosphere that contains the air we breathe. It extends from the Earth's surface up to about 10-15 kilometers (6-9 miles) in altitude.
6 Major masses affected the united states
The record is 6.
Interstates: I 15; I 80 Federal highways: US 6; US 50; US 93; US 95; US 395
Season 6 starts on September 23 (2009).
LOST aired on ABC. It had a total of 6 seasons.
I am not sure when it will air here but it airs in AUS March 12th @ 6:30.
freedom, efficiency, equity,security, stability and growth.
6 hours and 40 minutes
there are 6 major/ important ones but there are about 45
as many as you can count
Every Fri. at 6:30 I think.It airs on nicktoons on the weekdays
Colonel is higher ranking (O-6) than Major (O-4) in the Marines, Army, and Air Force. The comparable ranks in the Navy (and Coast Guard) are Captain (O-6) and Lieutenant Commander (O-4).
