Summer is the time of the second rainfall maximum during the year across Georgia, and the time of the main rainfall maximum in Florida. [ 46 ] [ 49 ] During the late summer and fall, tropical cyclones move into the region from the Atlantic and Gulf of Mexico, supplying portions of the area with one-quarter of their annual rainfall, on average.
World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes, also called the mid-latitudes (sometimes spelled midlatitudes) or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer (latitude 23°26′09.7″) and the Arctic Circle (66°33′50.3″) in the northern hemisphere and ...
A tropical cyclone can become extratropical as it moves toward higher latitudes if its energy source changes from heat released by condensation to differences in temperature between air masses; [20] From an operational standpoint, a tropical cyclone is usually not considered to become a subtropical cyclone during its extratropical transition. [26]
An extratropical cyclone is a synoptic scale low-pressure weather system that has neither tropical nor polar characteristics, being connected with fronts and horizontal gradients in temperature and dew point otherwise known as "baroclinic zones".
An extratropical storm absorbed the remnants of Tropical Storm Philippe. The combined systems became an extremely powerful nor'easter that wreaked havoc across the Northeastern United States and Eastern Canada. The storm produced sustained tropical storm force winds, along with hurricane-force gusts in many areas.
Hurricane Cristobal (2014) in the north Atlantic after completing its transition from a hurricane to an extratropical cyclone. Tropical cyclones often transform into extratropical cyclones at the end of their tropical existence, usually between 30° and 40° latitude, where there is sufficient forcing from upper-level troughs or shortwaves ...
(The term aseasonal refers to the lack in the tropical zone of large differences in daylight hours and mean monthly (or daily) temperature throughout the year. Annual cyclic changes occur in the tropics, but not as predictably as those in the temperate zone, albeit unrelated to temperature, but to water availability whether as rain, mist, soil ...
Lake-effect snow is produced as cold winds blow clouds over warm waters. Some key elements are required to form lake-effect precipitation and which determine its characteristics: instability, fetch, wind shear, upstream moisture, upwind lakes, synoptic (large)-scale forcing, orography/topography, and snow or ice cover.
