(12 points) Read the Map of Near-surface Weather System in the Northern Hemisphere (hPa) and answer the following questions. (1) According to the air pressure, ① the ground is

(1) High pressure and low pressure

(2) Northwest (north)

(3) After the cold front with low temperature and clear weather passes through, the ridge of high pressure will be controlled

(4) Affected by the cold front activity, it will experience a gale, rain and snow, and cool weather (2 points for every air, 12 points for * * *). In fact, cyclone is a low-pressure system, and anticyclone is a high-pressure system. ① The center of the earth is high pressure, which means high pressure center; ③ The center of the earth is low pressure, which means low pressure center.

(2) This question examines the formation of wind direction. The horizontal movement of the atmosphere is called wind, and the direct cause of the wind is the horizontal pressure gradient force, which is perpendicular to the isobar and points to the low pressure. At high altitude, the wind direction is only affected by horizontal pressure gradient force and geostrophic deflection force, and near the ground, the wind direction is also affected by friction force. The geostrophic force in the northern hemisphere moves to the right, so the northwest wind finally blows.

(3) This question examines common weather systems and weather. ④ The land is controlled by the ridge of high pressure. After the cold front passes through, near the ridge line of high pressure, after the cold front passes through, the weather is clear and the temperature is low.

(4) This question examines the frontal system and the weather. (5) The ground is controlled by the warm air mass at the moment and will be affected by the cold front, so the weather will be cloudy, windy, rainy and snowy. After crossing the border, the weather turned fine, the temperature dropped and the air pressure increased.

concept

the cold air mass actively moves to the warm air mass

the warm air mass actively moves to the cold air mass

a quasi-static front refers to a front with a small moving range.

Weather characteristics

Before crossing the border, it is controlled by a single air mass, and the weather is clear

It is controlled by a single air mass, and the temperature is clear

The cold and warm air masses are evenly matched, or the front moves slowly when it is blocked by terrain, or swings in an area for a long time, resulting in rainy and continuous weather.
