Trowal front
There are two different meanings used within meteorology to describe weather around a frontal zone. The term "anafront" describes boundaries which show instability, meaning air rises rapidly along and over the boundary to cause significant weather changes and heavy precipitation. A "katafront" is weaker, bringing smaller changes in temperature and moisture, as well as limited rainf… Webtrowal (Trough of warm air aloft by Canadian Avalanche Association and World Meteorological Organisation) Date: 15 August 2006: ... 1. cold front 2. warm front 3. stationary front 4. occluded front 5. surface trough 6. squall line 7. dry line 8. tropical wave 9. trowal: Width: 560:

Web[00:00:28] A TROWAL is a feature when occluded front and an occluded front simply means you have 2 colder air masses that come together and cut the warm air off from below. … WebTrowal Front forms Frontogenesis Front dissipates Frontolysis Cold air advances on a shallow layer of colder, heavier air Upper cold front Heavier cold air (trapped) begins to retreat Upper warm front Key is the tropopause. When there is a strong temperature gradient, there will be a strong pressure gradient resulting in strong winds.
A term favoured by Canadian forecasters during winter weather, TROWAL is used to describe a "tongue" of relatively warm/moist air aloft that wraps around to the north and west of a mature cyclone. Areas of intense lift and frontogenesis are commonly associated with TROWALs, and they are favoured regions for … See more The position of an occluded front on a surface weather analysis is often offset from the associated weather, which occurs at the TROWAL (short for TROugh … See more A trowal is indicated by junction of blue and red lines like the junction of cold and warm frontsaloft. See more WebIt is best analyzed between 750-550 milibars using equivalent potential temperature (theta-e). Areas of intense lift and frontogenesis are commonly associated with TROWALs, hence they are favored regions for heavy and/or prolonged precipitation. During a winter storm, the heaviest snowfall amounts frequently occur along and north of the TROWAL ...
WebDescription When large masses of warm air and cold air meet, they do not mix because of density differences. Instead, they form a front, usually hundreds of miles long. An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as … http://marrella.meteor.wisc.edu/cyclwkshp.html
WebMeanwhile, its associated warm front progresses more slowly, as the cooler air ahead of the system is denser, and therefore more difficult to dislodge. Later, the cyclones occlude as the poleward portion of the cold front overtakes a section of the warm front, forcing a tongue, or trowal, of warm air aloft. Eventually, the cyclone will become ...

The term has its origins analog to military operations as the armies in battle encounter each other at the front. There are two types of front: A. Cold Air front: If cold air advances, the air front is called cold air front B. Warm air front: If cold air retreats, it is called warm air front. the lion gate mycenaehttp://avcanada.ca/forums2/viewtopic.php?t=65967 the lion gate of mycenae
