Read the pictures and answer the following questions. (14 points) Figure A is a schematic contour map of a certain area in the world, and Figure B is a regional map showing Kabul and Karachi.

(1) The annual precipitation in Kabul is greater than that in Karachi (2 points). Kabul is located in the inland mountainous area, mostly due to topographic precipitation; (1) Although Karachi is located in the coastal area, the summer monsoon is not easy to reach and there is little precipitation. ( 1)

(2) The precipitation in Kabul is concentrated in winter and spring, which is influenced by the west wind (2 points); The precipitation in Karachi is concentrated in summer and influenced by the southwest monsoon (2 points).

(3) Features: the first day changes greatly, and the second day changes little (or the first day changes more than the second day) (1). Reason: Rivers are mainly replenished by meltwater of ice and snow, and the flow rate changes with temperature (1); On the first day, the weather was clear, the temperature difference between day and night was large, and the flow changed greatly day and night (2 points); The next day is cloudy, the temperature difference between day and night is small, and the variation of flow and runoff between day and night is small (2 points). (Other answers can be graded as appropriate)

Test analysis:

(1) It is not difficult to see from Figure B that the annual precipitation in Kabul is greater than that in Karachi. There is more precipitation in Kabul from June 1 1 to May of the following year, which is mainly located on the windward slope of the south branch of the west wind (the prevailing west wind is blocked by the Qinghai-Tibet Plateau and divided into two branches), and most of it is in topographic precipitation; Although Karachi is located along the coast, it is controlled by the subtropical high all the year round, with little precipitation (occasionally affected by the southwest monsoon in summer, with a little more precipitation).

(2) As can be seen from the figure, the precipitation in Kabul is concentrated in winter and spring, and it is influenced by the south branch of the westerly wind in winter and spring (the prevailing westerly wind is blocked by the Qinghai-Tibet Plateau and divided into two branches), forming precipitation on the windward slope of the mountain; Karachi is located on the northwest coast of South Asia. Summer is affected by the southwest monsoon, and precipitation is concentrated in summer.

(3) From the figure, we can directly get the two-day flow change characteristics of the river: the first day changes greatly, and the second day changes slightly. As Reach A is located in the upper mountainous area of the river, the river is mainly replenished by melting water of ice and snow, and the flow rate changes with temperature. On the first day, the weather was fine, the temperature difference between day and night was large, and the flow changed greatly between day and night. The next day was cloudy, with small temperature difference between day and night, and small variation of flow and runoff between day and night.
