If you look for the area in white here over the tropics,
we can see that, that area of high percentage
of cloud cover moves from the south to
the north over the course of the year.
You can see that the cloudiest locations are usually in the tropics,
so in September somewhere between 10 to 20 degrees Nnrth.
And with areas that are the least cloudy just to the sides, so
over here in the Sahara where there almost no cloud cover at all.
Next in the near persistent cloud cover of the ITCZ.
This is due to descending node of a circulation pattern
called the Hadley Cell.
You can also see that the poles are very cloudy over winter months.
So during July, August In September,
you have high cloud cover values over Antarctica.
Whereas in December, January and February,
you have high cloud cover values over the Arctic.
These values of high cloud cover are also associated with values of
high precipitation.
So, if we change our climate property to total precipitation,
we can see how these are associated with each other.
So, over the course of the year, you can see that this area of the highest
precipitation moves from the south to the north, which is associated with the ITCZ.
