How do extratropical cyclones form
WebWhile extratropical cyclones form and intensify in association with fronts, there are small-scale cyclones that appear in the middle of a single air mass. A notable example is a class of cyclones, generally smaller than the frontal variety, that form in polar air streams in the wake of a frontal cyclone. Weba source of warm, moist air derived from tropical oceans with sea surface temperatures normally in the region of, or in excess, of 27 °C; winds near the ocean surface blowing from different...

However, some intense extratropical cyclones can become warm-core systems when a …
WebThe Saffir-Simpson Scale classifies hurricane-strength tropical cyclones into five categories (1-5) based on maximum sustained wind speed. Major hurricanes (also called intense hurricanes) fall into categories 3, 4, and 5 on the Saffir-Simpson Scale. A super-typhoon reaches category 4 or 5 on the Saffir-Simpson Scale. Category Miles Per Hour WebExtratropical cyclones are large swirling storm systems that form along the jet stream between about 30 degrees and 70 degrees latitude.

WebExtratropical cyclones draw energy from the horizontal variation of temperature in the atmosphere; i.e., from the baroclinic structure of the atmosphere. Clouds form in response to the vertical air motions within baroclinic waves and are usually concentrated along warm, cold, and occluded fronts.
WebThe westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
