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 in beginning of spring, beginning of spring only means that spring has started, and the temperature has started 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 9 and June 9, 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 takes half a year. Although it gradually warms up in spring, it is still cold in the morning and at night 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, and it is lower in annual range (the temperature days in low latitudes and annual range are lower than those in high latitudes).

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 in mountainous areas at the same latitude is worse than that in plains and smaller in annual range).

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 (sunny in rainy days, less in annual range).

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

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