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 ...
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 ...
This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones). Most high-and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by the location of Rossby waves in their respective hemisphere.
Breathtaking satellite imagery of a stunning mid-latitude cyclone off the West Coast that will steer a significant atmospheric river into California tomorrow.
A bomb cyclone, also referred to as explosive cyclogenesis or bombogenesis, is a mid-latitude cyclone that has rapidly intensified. A cyclone is a low-pressure weather system - one where the ...
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.
A cyclone barrelling towards southeast Africa for the last four days caused widespread devastation in Mayotte after it struck the French oversea region as the most powerful storm in 90 years.
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.
