(16) Read the schematic diagram of the weather situation in some areas of China (Figure 16), and answer the question according to what you have learned: What is the air pressure at (1)A? (=NationalBureauofStandards) .. 1) high pressure and sunny weather

(2) Northwest (North)? b？

Isobars at B are denser than those at C, and the horizontal pressure gradient force is greater.

(3)? second

Strong wind, rain and snow

This topic studies weather systems.

(1) According to the law of isoline "higher than high and lower than low", it is judged that A is the high pressure center. High pressure control is dominant in settlement.

Airflow, so the weather is good.

(2) The painting direction is distributed according to the isobar: from high pressure to low pressure, the northern hemisphere leans to the right; Wind power: The denser the isobar,

The stronger the wind;

(3) Beijing is affected by the cold front at this time, and the weather characteristics affected by the cold front are windy, little rain and cooling.
