The picture below is the distribution map of near-surface weather systems in a certain area (unit: hPa). Read the picture to answer the following questions. (10 points) (1) D ground is affected by air pressure
(1) High; clear; rising
(2) D; clear weather, weak atmospheric attenuation during the day, high temperature, and atmospheric reverse radiation at night Weak, low temperature
(3) Cold; temperature drops?
(4) North/northwest; E; isobars at E are more dense
This question examines weather patterns.
(1) The central air pressure at D is higher than the surrounding area, so it is a high-pressure center; the high pressure is controlled, and downdrafts prevail, so the weather is sunny; C is a low-pressure center, so updrafts prevail;
< p>(2) Location D is controlled by high pressure, so the weather is sunny and the temperature varies greatly between days;(3) The diagram reflects that the cold front is about to move to location A, so location A is about to experience a cold front weather process , the temperature drops.
(4) The direction at E can be distributed by isobars, considering that the horizontal pressure gradient force is perpendicular to the isobars, pointing from high pressure to low pressure, and deflecting to the right in the northern hemisphere, forming northwest winds. If the isobars at E are denser, the horizontal pressure gradient force will be larger, so the wind will be stronger.
