When will it be warm after the New Year?

Taking 2023 as an example, it began to warm in March after the year, when the temperature rose obviously.

After the New Year-usually in1~ February, although it is already beginning of spring and beginning of spring only represents beginning of spring, the temperature starts to rise, but the overall temperature is still relatively low, and there will be late spring chill. Moreover, the Chinese New Year is still May 9th and June 9th, and it will take another month or so to come out.

As far as previous years are concerned, spring is a transitional process from cold winter to hot summer, and the time span is as long as half a year. Although spring is getting warmer, it is still cold in the morning and evening, because the number of cold air activities is still relatively frequent.

Factors affecting temperature level

1, Latitude (decisive factor): It affects solar height, day length, solar radiation and daily range, which is lower in annual range (the temperature days in low latitude and annual range are lower than those in high latitude).

2. Topography (height, topography): shady slopes, sunny slopes, mountains, plains, valleys, and basins at different altitudes (for example, the topographic heat in valley basins is not easy to dissipate, and the tall terrain blocks the winter wind, and the daily range of mountains at the same latitude is smaller than that in plains, and the annual amplitude is smaller).

3. Location of land and sea: The strength of ocean leads to the annual variation range of temperature.

4. Ocean current (warm current: warming and humidifying; Cold current: cooling and dehumidification).

5. Weather conditions (the temperature in rainy places is sunny, and the annual variation is smaller than that in rainy places).

6. Underlying surface: ground reflectivity (high snow reflectivity and low temperature); The daily temperature and annual range of green land are less than that of bare land.

7. Human activities: heat island effect, greenhouse effect, etc.
