The picture shows "Schematic Diagram of Distribution of Pressure Belt and Wind Belt". Look at the picture and complete the question 19-20. The solar terms shown in this picture are () A. Equinox B. Summer solstice C. Winter. According to the seasonal movement law of the pressure belt wind belt, the pressure belt wind belt moves with the seasonal movement of the direct point of the sun. As far as the northern hemisphere is concerned, it moves north in summer and south in winter. According to the analysis of reading the map, the equatorial low pressure belt is just around 0, which shows that the position of the global pressure belt wind belt is impartial at this time, and it is the distribution map of the pressure belt wind belt when the sun shines directly at the equator, that is, whether the solar terms indicated on this map are vernal equinox or autumn equinox.
