Question 1:A?

Question 2: B?

Question 3:B

Test analysis:

Question 1: Look at the map. According to the value of isobar on the map, it is controlled by continental high pressure and ocean low pressure in the northern hemisphere, which means 1 month, and it is winter in the northern hemisphere. A is right. B, c and d are all wrong.

Question 2: According to the isobar in the figure, A is located on the left side of the low pressure center in the northern hemisphere and in front of the cold front of the frontal cyclone. The cold front precipitation is behind the front, so it is sunny in A, and A is wrong. B is behind the cold front. How big is the storm in the season shown in the picture? B is right. C is the high pressure center and belongs to the anticyclone in the northern hemisphere. Winter is controlled by cold and high pressure, so the climate is cold and dry, and C is wrong. Ding is located on the ridge of high pressure and cannot be a quasi-static stop front. D is wrong.

Question 3: Meteorological departments need to refer to many information such as land and sea position, terrain distribution, administrative division distribution, air pressure distribution map and so on when making weather situation map, and need to use GIS technology to analyze and process all kinds of information. RS is remote sensing, so it can't analyze and process data. A is wrong. GPS is mainly for positioning and navigation, and c is wrong. The fault of digital earth lies in transforming all kinds of information into data, realizing transmission, and enjoying and D on the network.
