Ocean front effects on development and maintenance of the synoptic low pressure and its feedback to the ocean surface layers.

在日本南部黑潮-黑潮延伸区的海表面温度(SST)锋面区域，研究了海洋-大气的影响。锋面热通量较强的区域上空存在楔形低海平面气压(SLP)。在数值试验中，用规定的锋面海温强迫的模式成功地再现了观测特征。相比之下，由平滑的SST强制建立的模型无法再现特征。这些观测和数值结果表明，海洋的热释放使低层大气变暖，然后在该地区形成静力调整的SLP极小值。

Ocean-to-atmosphere effects are examined in the sea surface temperature (SST) frontal region along Kuroshio-Kuroshio Extension south of Japan. A wedge-shaped low sea level pressure (SLP) is found over the region with intense surface heat fluxes along the front. In the numerical experiments, the model forced by the prescribed SST with the front successfully reproduced the observed features. By contrast, the model forced by the smoothed SST failed to reproduce the features. These observational and numerical results show that the heat release from the ocean warms up the lower atmosphere and then form SLP minimum over that region as the hydrostatic adjustments.
