What is the relationship between the geographical location of the city and the temperature?

1, other things being equal, the higher the latitude of the city, the lower the annual average temperature.

2. Other things being equal, the higher the altitude of a city, the lower the annual average temperature.

3. Other things being equal, the farther a city is from the ocean, the lower the annual average temperature.

Take Longxian County, China as an example. It is located in the west of Daxinganling-Lanzhou-Gangdise Mountains in China. It belongs to the transitional temperate continental climate in non-monsoon area, but it will also be accompanied by monsoon factors, and sometimes it will show monsoon characteristics. According to the topographical features, the territory can be divided into three climatic zones from north to south:

First, the semi-arid temperate climate zone in the north;

Because it is located in the inland area of northwest China, far away from the ocean and blocked by mountains, it is difficult for ocean water vapor to reach in large quantities. This position forms this special climate.

Ⅱ. Warm, cool and semi-humid areas in shallow mountainous areas of south-central China; Because of its low altitude, the humid air flow from the Pacific Ocean will have some influence, resulting in a warmer and wetter climate in this area.

Extended data

The temperature in a certain place changes periodically not only because of the change of solar radiation, but also because of the movement of the atmosphere rather than periodically. The change of actual temperature is the result of the interaction between these two aspects. If the former plays a big role, the temperature changes periodically; On the contrary, it shows an aperiodic change.

However, from the general trend and most cases, the periodicity of daily and annual temperature changes is still the main one. Various components in the heat balance, such as radiation difference, latent heat and sensible heat exchange, are affected by different control factors. Astronomical factors such as latitude and season have obvious zonal and periodic characteristics.

However, the nature, topography and weather conditions of the underlying surface, such as cloud cover and atmospheric humidity, all have non-zonal characteristics. At the same time, the influence of these factors is different in different places, so the temperature distribution caused by the change of heat budget is also uneven.
