Anticyclone in Mauritius

Anticyclones in Mauritius occur during the winter season. Anti-cyclone which is also called as high pressure area is a big spiral circulation system of wind having normally a diameter between 1600 to 8000 kilometres. The wind flows in the clockwise direction in Northern Hemisphere and counterclockwise in Southern Hemisphere. Thus in Mauritius and South Indian Ocean, unlike tropical cyclones, anticyclones flows in counter-clockwise direction. Anticyclone produces dry and cool air. This is why during anticyclone in Mauritius, there is a slight decrease in temperature during the day and even more decrease in temperature at night.

• The sky is normally clear with no cloud cover over the island.
• There is a slight decrease in temperature making day cooler and night being even more cooler.
• Fog and frost are formed at night, especially on Central Plateau.
