The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if a tropical cyclone has intruded into the mid latitudes.
As the storm moved east on January 8 and 9th, the cyclone remained negatively tilted, and formed a tornado outbreak in the Deep South, whilst portions of Indiana recorded record low pressure. Strong mid-level to low-level flow contributed to extreme weather, allowing storms to mature at the mesoscale , with strong moisture return near the coast ...
The effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall, and tornadoes. The destruction from a tropical cyclone, such as a hurricane or tropical storm, depends mainly on its intensity , its size, and its location.
The Fujiwhara effect – which describes the rotation of two storms around each other – is one of meteorology's most exquisite dances. It's most common with tropical cyclones such as typhoons or ...
A bomb cyclone is defined as a mid-latitude cyclone over the Pacific Ocean that drops 24 millibars — a measure of atmospheric pressure — over 24 hours. This particular bomb could drop 50-60 ...
NOAA's GOES West satellite captured enhanced color imagery of a powerful mid-latitude cyclone and atmospheric river impacting Northern California, the Pacific Northwest and British Columbia this week.
These systems may also be described as "mid-latitude cyclones" due to their area of formation, or "post-tropical cyclones" where extratropical transition has occurred, [16] [17] and are often described as "depressions" or "lows" by weather forecasters and the general public.
Extratropical cyclones, sometimes called mid-latitude cyclones, are a group of cyclones that occur in the middle latitudes of the Earth, and which have neither tropical nor polar characteristics. They are connected with fronts and feature changes in temperature and dew point horizontally, otherwise known as "baroclinic zones".
