The picture below shows a simplified diagram of the weather situation near the surface on a certain day. Read the picture and complete the following questions. (1) In the picture, the order of air pressures from high to low in A, B, C and D is ____
(1) According to the values of isobars, it can be judged that the air pressure value in place A is 1020 hectopascals, the air pressure value in place B is greater than 1015 hectopascals and less than 1020 hectopascals, and the air pressure value in place C is greater than 1000 hectopascals and less than 1020 hectopascals. 1005 hPa, and the air pressure value in Ding is 1010 hPa. In the figure, the air pressures of A, B, C, and D in descending order are A, B, D, and C.
(2) The magnitude of the wind force depends on the density of the isobars. The sparser the isobars, the smaller the wind force. Among the four places A, B, C and D, B has the smallest wind force.
(3) Specifically, the wind direction flows from high pressure to low pressure, and the northern hemisphere deflects to the right. The wind direction in A is northwest; in D, it is located in front of the cold front, affected by a single warm air mass, and the weather is clear.
(4) In the horizontal direction of the northern hemisphere cyclone, the airflow flows counterclockwise from all sides to the center. Beijing is located behind the cold front, and there will be rainy weather. After that, the front will move to the southeast. After the cold front passes, the weather change in Beijing is the temperature Descending, air pressure increased, and the weather became clearer.
(5) The low pressure in the picture is called a cyclone in terms of air flow conditions. The air flow rises in the vertical direction. During the rising air flow, it is easy to condense clouds and cause rain, resulting in cloudy and rainy weather.
So the answer is:
(1) A, B, D, C
(2) B? The isobars are the sparsest and the horizontal pressure gradient force is the smallest
(3) Sunny northwest wind
(4) Cloudy and rainy? Southeast? Decrease and increase to sunny
(5) Cyclone? Cloudy and rainy
