Question 6

Global Weather -Low Level Winds, Fronts and the ITCZ

Refer to the following diagram. This represents which time of year, JANUARY or JULY

Answer 6

JANUARY

• The ITCZ is favouring the south
• It is the Southern Hemispheres Summer
• This leaves the Northern Hemisphere colder, making the air more dense
• Denser air is heavier, so higher pressure over cold land surface in NH
• Lower pressure over large land surfaces in the SH
