true 14

15. The areas of abundant rainfall on the earth tend to be
near the equator and in midlatitudes. 15

16. Why do westerly winds prevail at upper altitudes?
rotation of the earth and equator to pole temperature contrast 16

17. Surface high pressure zones are usually associated with
clear or nearly clear weather. 17

18. Jet streams are associated with fronts because of the
large temperature gradient. 18

ITCZ. 26

27. The definition of the word 'monsoon' means
seasonal wind shift. 27

28. A primary factor causing monsoon circulations is
greater temperature changes over continents compared to oceans. 28

29. circulation patterns in the atmosphere.

mesoscale 30

31. The greater strength of jet stream winds during winter is due to
greater horizontal temperature contrasts. 31
