中文摘要:
      根据西太平洋海域弱风、高温、潮湿的大气状态特征,提出了在光滑面存在粘性副层气流中的廓线的层结订正方案。用此模式对西太平洋暖池区TOGA COARE IOP期间,在向阳红5号船(2°S,154°E)获取的海面风、温、湿梯度资料进行了处理。计算结果显示西太平洋暖池区贴水层气流中不稳定层结占50%-80%,其中很不稳定的占10.3%;该海区海气通量和整体交换系数受层结影响远大于受风速的影响;海气通量和整体交换系数随不稳定程度增加而增大,在相同风速下量值可相差4倍以上;其变化范围为0.3×10-3-3.2×10-3。由此可见,层结的影响使它们的变化大于其它海区的结果。在u<10=0-10m/s范围内,中性化整体交换系数平均为CDN=1.2×10-3,CHN=1.14×10-3,CEN=1.19×10-3,与Large和Pond(1981,1982)不稳定条件的研究结果相差无几。
英文摘要:
      A stratification modified model of the profiles is developed for a viscous sublayer of light wind,high temperature and humidity,over a smooth sea surface.The data of the gradient of wind,temperature and humidity near the sea surface of "warm pool" in the Western Pacific,obt ained by XiangYang Hong #5 R/V during TOGA COARE IOP,are calcul atedusing this model.Computing results show that there are about 50%-80% observations in unstable state,among them 10.3% are strong unstable.The effect of stratificat in on the air-sea fluxes and bulk transfer coefficients are much stronger than that of wind.These fluxes and coefficients increase with the increasing unstability by a fact or of 5 under the same wind.They vary from 0.3×10-3 to 3.2×10-3.It can be seen that the variations ae larger than those at other sea area justo wing to the effect of stratification.
