Test analysis:

Question 1: Judging from the latitude and longitude, the illustrated area is located in the southern hemisphere. Tropical storms are cyclones that converge clockwise in the southern hemisphere. Located in the land P, northeast wind blows in the east, southeast wind blows in the south, southwest wind blows in the west and northwest wind blows in the north. The wind direction observed by an observatory is southeast wind, that is to say, the observatory is located in the south of point P. After observing the northeast wind, the observatory is located in the east of the typhoon center, and in the northwest wind, it is located in the north of the typhoon center. Therefore, the typhoon center moves to the southwest first, and then to the southeast. B. A, C and D are all wrong.
