Senior one geography weather system 8 ~ 9 questions explain! Thank you very much !

8. Air flows horizontally from high pressure to low pressure. According to the wind direction, it is obviously a low-pressure center (air gathers from all sides to the center in the horizontal direction).

The wind direction of 9 and 4 is the northwest monsoon formed by the northeast trade wind in the northern hemisphere moving south across the equator and entering the southern hemisphere (to the left) under the bias of floor tiles, so it is summer in the southern hemisphere at this time, and the answer is D.

Typhoon is the center of low pressure, so A is wrong. The northwest monsoon blows from the ocean to Australia, so the tropical grassland climate in northern Australia enters the rainy season. B Wrong, the Brazilian plateau has a savanna climate. Although it is rainy season, it has nothing to do with four winds in the picture. C is wrong, and the correct answer is D. The cause of the South Asian summer monsoon is that the southeast trade winds in the southern hemisphere deflect to the right across the equator.
