How to analyze the temperature and precipitation map of geography and how to judge the city by him

Take the northern hemisphere as an example:

1 Look at the change of temperature curve: analyze the value and difference between the highest temperature month and the most Leng Yue. If the annual temperature is above 15℃ and changes to tropical (as shown in Figure B), if the most Leng Yue temperature is above 0℃ and changes to subtropical (as shown in Figure A), if the most Leng Yue temperature is below 0℃ and changes to temperate monsoon or temperate continental climate (as shown in Figure C); If the maximum Leng Yue temperature is above 0℃ with little change, it is a temperate maritime climate.

2 Look at the total amount and seasonal variation of precipitation column. If there is more precipitation in each month of the year (as shown in Figure B), the tropical rain forest climate with a total amount of 2000mm, the monsoon climate with more precipitation in summer and less precipitation in winter (as shown in Figure C), and the Mediterranean climate with more precipitation in winter and less precipitation in summer (as shown in Figure A).

How can he judge the city?

Each climate type has its representative city, so we can judge the regional climate type first, and then determine the city by combining the topic materials. As shown in figure a, it is distributed on the west coast of the mainland at 30-40 degrees north and south latitude. If it is on the Mediterranean coast-Rome, Athens, etc. If it is in western North America-San Francisco and Los Angeles, if it is in western South America-San Diego, Australia-Perth, and southern Africa-Cape Town.
