Occluded fronts usually form around mature low pressure areas.There are two types of front occlusions, warm and cold, depending on the temperature contrast: . In a cold occlusion, the cold air mass that overtakes the warm air mass ahead is colder than the cool air at the very front and plows under both air masses, and often has the characteristics of a cold front.
Occluded front depiction for the Northern Hemisphere. An occluded front is formed when a cold front overtakes a warm front, [10] and usually forms around mature low-pressure areas, including cyclones. [2] The cold and warm fronts curve naturally poleward into the point of occlusion, which is also known as the triple point. [11]
The weather associated with an occluded front includes a variety of cloud and precipitation patterns, including dry slots and banded precipitation. Cold, warm and occluded fronts often meet at the point of occlusion or triple point. [28] A guide to the symbols for weather fronts that may be found on a weather map: 1. cold front 2. warm front
The weather usually clears quickly after a front's passage. Some fronts produce no precipitation and little cloudiness, although there is invariably a wind shift. [19] Cold fronts and occluded fronts generally move from west to east, while warm fronts move poleward. Because of the greater density of air in their wake, cold fronts and cold ...
Occluded fronts form when a faster-moving cold front catches up to a warm front, and the temperature after the frontal system passes may rise or fall. [29] As the frontal system approaches, cirrostratus clouds will thicken into altostratus clouds, which then gradually thicken further into nimbostratus clouds. [2] [30] If the frontal system is ...
"These are the types of weather systems that even bring cold air to Florida," Merwin said. "You know, there’s only maybe one or two times a year where we get a chunk of arctic air that really ...
Cold subsides when the vortex restabilizes and drives the arctic air back north. January’s freeze-out comes after December started cold, but finished out unusually warm across most of the country.
"Back in the 1950s and 60s, there were experiments to try to weaken weather systems, but the results were really inconclusive," Dr. Kristen Corbosiero, a meteorologist and professor University at ...
