What is the impact of the large amount of water in Lake Baikal on the surrounding climate?

A large number of Lake Baikal plays an obvious role in regulating the continental climate on the lakeside, with abundant sunshine, so the temperature difference between day and night in the lake area is small, and the temperature difference is also small all year round, with warm winter and cool summer. The hottest month, the hottest Leng Yue, the ice age and the ice melting period are all delayed by one month compared with the surrounding areas. In winter, the lake freezes, releasing latent heat, reducing the cold in the surrounding areas in severe winter; In early summer, the lake thawed and absorbed a lot of heat, which reduced the heat in coastal areas, and the temperature of the lake was 6℃ lower than that in surrounding areas. But the lake itself is always cold. Even in the warmest season, the temperature of the lake is always between 7℃ and 9℃.
