Question

Describe the atmospheric circulation cells in the Northern Hemisphere. At which latitudes does air move vertically? Horizontally? What are the trade winds? The westerlies? Where are deserts located? Why? What is ocean-surface salinity like in these desert bands?

Answer 1

Answer: The atmospheric circulation

in the Northern Hemisphere would move to the right as warm air would rise, it is called a Hadley cell. Air moves vertically at the boundaries between convention cells, and one example would be at the Earth's equator. Air moves horizontally at places with in the convention cells. An example of horizontal air movement would be in doldrums Hadley cells as they shift from the horse latitudes towards the doldrums. The westerlies are surface winds of the Ferrel cells that flow between the horse latitudes and the and the boundaries of polar cells in each Hemisphere. Deserts occurs at the latitude of 30 degree. This is where the Hadley and Ferrel cells intersect and create more evaporation than precipitation in these areas. Ocean salinity is the highest in these desert bands.
