Why is Sheng30 colder than Ningbo?

The reasons why Shengsan is cooler than Ningbo are as follows:

1. Ningbo is located on the east side of Shengsan, close to the ocean, and has a humid monsoon climate in the north subtropical zone. The southern part has the characteristics of transition to the subtropical zone. In winter, the temperature is higher than Sheng30 due to the influence of warm currents.

2. Frequent cold air activities are closely related to the large periodic fluctuations of the westerly circulation in the middle and high latitudes of Eurasia. The blocking high pressure in the Ural Mountains and the periodic strengthening of the East Asian trough triggered three cold wave weather processes.

3. The continuing impact of the Nina incident. Under the background of La Ni?a, the meridional direction of the mid-to-high latitude circulation in Eurasia is large and its periodic fluctuations are obvious, which provides favorable climate background conditions for cold air to frequently affect the Sheng30.
