The diagram to the right corresponds to a in the hemisphere.

Explanation / Answer

3. Near the equator, atmospheric pressure tends to be low

4. At the poles, the atmospheric pressure tends to be highest

5. Air moves from low to high pressure. In the diagram B, air is moving from surface to upper level, that is why this diagram corresponds to low pressure at the surface.

6. The diagram B corresponds to convergence at the surface.

In atmosphere, convergence of horizontal air causes air to rise hundreds of kilometres. Air rises from low pressure and move towards high pressure. Converging air results into cyclone.

7. The diagram A corresponds to divergence at the surface.

8. In coastal areas, the land tends to heat more than ocean during the day resulting in low pressure which results in a sea breeze.   

9. In coastal areas, the land tends to cool more than ocean in the evening resulting into high pressure which results in a land breeze.

10. The Coriolis Effect deflects winds to the right in northern hemisphere.

11. The diagram corresponds to an anticyclone (as air moving from a high pressure center towards low pressure surroundings) pressure cell in northern hemisphere (because it is clockwise).

12. The diagram corresponds to a cyclone pressure cell (as air is moving towards a low pressure zone, situated in the center) in southern hemisphere. (Because it is anticlockwise).

The diagram provided is too unclear to obtain any information like numbers, scale. I could not read the numbers.

18. At horse latitudes, near 30 degree N and S, atmospheric pressure tends to be high and the air tends to     in the vertical and the climate tends to be very calm, with little precipitation.

19. Trade winds above and below the equator tends to blow from east to west (easterlies).

20. At mid latitudes, 450 N and S, the winds tends to blow from west to east (Mid latitude westerlies).
