What type of weather does a maritime polar air mass bring?
Maritime polar (mP): Cool and moist. They usually bring cloudy, damp weather to the USA. Maritime polar air masses form over the northern Atlantic and the northern Pacific oceans. They most often influence the Pacific Northwest and the Northeast.
Where do air masses acquire their temperature and humidity characteristics?
Where an air mass receives it’s characteristics of temperature and humidity is called the source region. Air masses are slowly pushed along by high-level winds, when an air mass moves over a new region, it shares its temperature and humidity with that region.
Which air mass is most likely to come from the Caribbean?
Maritime tropical air forms in subtropical regions such as the Gulf of Mexico and the Caribbean Sea. It is associated with warm, humid weather and thunderstorms. 2. Maritime tropical air is most commonly found in the United States during the summer months.
What is the difference between a cP and a cT air mass?
The humidity characteristic is derived from the type of surface over which the air mass sits. The two main surface differences on earth are LAND and WATER….
| name of air mass | description | |
|---|---|---|
| cT | continental tropical | dry and warm |
| mP | maritime polar | moist and cold |
| cP | continental polar | dry and cool or dry and cold |
Is the air at the beach humid or dry?
It can change each day and is generally different in locations that have different climates. On the interior of continents, where the air is further from oceans and less able to pick up vapor from the sea surface, there is generally lower humidity than places that are near the ocean.
What two characteristics define air masses?
Temperature and humidity are two characteristics used to classify air masses.
What type of weather does a warm front bring?
Warm Front Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth’s surface.
What type of weather do occluded fronts bring?
An Occluded Front forms when a warm air mass gets caught between two cold air masses. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation. Occluded fronts usually form around mature low pressure areas.
