| 摘 要： | 用数值方法研宄穿透性太阳短波辐射对混合层深度的影响时,有些学者人为地设定了风速和热通量。这种做法可能会出现风速和热通量数值不匹配的问题。为了弥补这一缺陷,本文采用国内外常用的块体公式计算热通量的方法来代替人为设置,并以北太平洋为例,研究了穿透性太阳短波辐射对海洋混合层深度的影响。结果表明:低风速(U10<10m／s),且海表短波净辐射处于40～200 W／m2时,穿透性太阳短波辐射对混合层深度影响很显著;高风速(U10>10m／s)和短波净辐射高值区(S*(0)>200 W／m2),穿透性太阳短波辐射对混合层深度的影响较小。

| Abstract: | The wind speed and net heat flux are often set arbitrarily by some researchers in recent studies when studying the effects of penetration radiation on the mixed layer depth, which may lead to mismatch between the two variables. In order to solve this problem, bulk formulas were used to calculate the heat flux across the air-sea surface and to study the effects of penetration radiation on the mixed layer depth in the North Pacific Ocean. The results show that the penetration radiation has significant effects only under low wind speeds (<10 m/s) and net short wave radiation ranging from 40 to 200 W/m2. On the contrary, the effects can be neglected when the wind speed exceeds 10 m/s or the net short wave radiation exceeds 200 W/m2. |
