Low pressure, tropical cyclones, cyclone Pam, Asia Monsoon Flashcards
Low pressure is when
Air warms and rises leading to low pressure at the surface.
When do tropical storms in the Northern Hemisphere occur?
Between June and November it peaks in September
When do tropical storms in the Southern Hemisphere occur?
Between November and April
What are tropical storms are also known as
hurricanes
typhoons
cyclones
Cyclones form when the sea temperature is
27 degrees C
Towering clouds and torrential rain is formed when
The warm sea water heats the air above it, causing it to rise, creating an area of very low pressure in the atmosphere.
As the air moves towards the centre of the low pressure it spirals upwards into the atmosphere. This is due to the Earth’s rotation known as the
Coriolis Effect.
