The weather forecast of Leshan tomorrow

Shanghai and Taipei belong to the coastal areas, where there is much water and the specific heat capacity of water is large. Xining and Lhasa belong to inland areas, with sandy soil as the main surface and small specific heat capacity of sandy soil.

Compared with land, water with the same quality absorbs the same heat during the day, and the temperature of water rises less, while the temperature of sand and gravel soil rises more, so the temperature rises lower in Shanghai and Taipei, and higher in Xining and Lhasa. At night, when the same amount of heat is released, the temperature of water drops less and the temperature of sand and gravel drops much, so the temperature in Shanghai and Taipei drops less, and the temperature in Xining and Lhasa drops much, so the daily temperature difference between Xining and Lhasa in inland areas is larger than that in Shanghai and Taipei in coastal areas.

So choose a.
