问题一:对流层“气温垂直递减”的形成原因在大气分层中,对流层和人类生产生活的关系最为密切。一般情况下,对流层的气温随高度的增加而降低,大约每升高1000米,气温下降6℃,即气温的垂直递减率为0.6℃/100米。在具体的教学中,教师解释对流层“气温垂直递减”的原因是“地面长波辐射是近地面大气的直接热源,距地面越远所获热量越少,温度越低”[1-2]。可是如果我们仔细推敲这一解释,很容易在逻辑上陷入矛盾。
Problem one: the formation of the troposphere “vertical temperature decrease ” reason In the atmosphere stratification, the troposphere and human production and life are most closely related. Under normal circumstances, the tropospheric temperature decreases with height, about every 1000 meters elevation, the temperature dropped 6 ℃, the vertical temperature decline rate of 0.6 ℃ / 100 meters. In specific teaching, the teacher explained that the tropospheric “vertical temperature decrease” is because “long-wave radiation on the ground is a direct source of heat in the near-surface atmosphere, the less heat it gets from the ground, the lower the temperature” 2]. However, if we scrutinize this explanation carefully, it is easy to be logically in conflict.
