Question

How does latitude determine wind patterns?

Answer 1

The angle of incidence of solar radiation is dependent on both the latitude and Earth's obliquity. Consequently, there are quantitative day-night and seasonal variations that make wind patterns.

Explanation:

In the absence of obliquity `23.4^o` to the normal to ecliptic, the

angle of incidence of solar radiation will be just the latitude. But the

obliquity gives this angle the oscillatory range " latitude `+- 23.4^o`

", over a year.

This causes temperature and density changes of atmosphere near

land and sea surfaces that produce wind currents up, down and

across.
