Extratropical cyclones play a critical role in distributing heat, moisture, and momentum across different regions of the planet. They are the main atmospheric systems driving weather patterns between the subtropics and high latitudes. For people living in these areas, the experienced changes in temperature, humidity, and weather conditions like rain,... [Read More]

Approximately 70 to 90% of the total precipitation that occurs in many regions across the mid and high latitudes in the Southern Hemisphere is directly caused by extratropical cyclones and their associated fronts. The damage potential of precipitation from these systems is quite significant, potentially resulting in billion-dollar economic losses... [Read More]

The Southern Ocean is often referred to as a “graveyard” for cyclones that originate from lower latitudes. This region has been identified by several authors as one of the most crucial areas for the cyclolysis of extratropical cyclones in the Southern Hemisphere (SH). While several cyclones from the mid-latitudes travel... [Read More]
