1.山顶与山谷(平原)的日温差比较在学习山谷风的时候,会发现山坡白天升温快,晚上降温快,按理说山顶的日温差应该大于山谷地区,而实际而并非如此。山谷风里所说的山坡是较大范围的下垫面。白天,山坡受热,空气增温快,但山谷中同高度的空气,由于距地面较远,增温较慢;夜间,山坡辐
1. Comparison of diurnal temperature difference between the summit and the valley (plain) When studying the valley wind, we find that the hillside warms up fast during the day and decreases rapidly at night. Theoretically, the daily temperature difference at the top of the mountain should be greater than that in the valley, which is not the case. The mountain slopes in the valley winds are a wide range of underlying surfaces. During the day, the hillside is heated and the air temperature increases quickly, but the air with the same altitude in the valley is slowed down due to being farther away from the ground. At night,
