These are known as the Subtropical Highs . The seasonal intensification of the Subtropical Highs should be related to the seasonal changes in temperature over land and ocean surfaces. The latitudinal shifting of the Subtropical Highs should be controlled by the seasonal movement of the Intertropical Convergence Zone . The Intertropical Convergence Zone moves north in summer and south in winter. Are the Subtropical Highs influenced by this movement.
Atmospheric pressure is influenced by temperature.
In terms of temperature, what happens to ocean surfaces at this latitude when compared to adjacent land surfaces. The Mid-Latitude Cyclone . In the Northern Hemisphere during the winter, another very strong high pressure region develops. Examine Figure 3.10.
