During the May Day holiday this year, Mr. Wang, who traveled abroad, climbed to a place and determined his position through GPS positioning (pictured). Look at the map.

The geographical coordinates of (1) A are 30 degrees south latitude and 60 degrees west longitude, so it is located in the western hemisphere.

(2) The time in the northern and southern hemispheres is the same, but the seasons are opposite. 30 S can be judged to be located in the southern hemisphere, and the May Day holiday in the northern hemisphere is the winter half year in the southern hemisphere. The length of day and night in this season is short, and the length of day will become shorter around June 22nd.

(3) There are different directions on the map. Longitude indicates the north-south direction, and latitude concentration indicates the east-west direction, so it can be judged that A is located in the southwest direction of B, and the contour line of B protrudes into a valley in the altitude direction, which is easy to form a river.

So, the answer is: (1) 30 s, 60w；; ; West; (2) The days are short and the nights are long; Short; Around June 22; (3) Southwest; Maybe.
