The main effect of them is to heat the lower troposphere, but cool the surface, so the presence of dust may cause a stabilizing effect on the temperature lapse rate, then affect the ocean low level stratus cover.
沙尘的辐射效应主要体现在冷却海表面而加热低对流层,因此沙尘有可能通过影响大气垂直稳定度从而影响海洋层云。
A Study of Macro-and Microscopic Features and Precipitation Mechanism of Spring Precipitating Stratiform Clouds in Henan Province;
河南省一次春季层状云系降水的宏微观特征及降水机理研究
physico-chemical model of stratiform clouds is used to evaluate the acidification of precipitation and wet removal of pollutants in South China in spring season and results from the model are consistent with the mean field data.
运用一维时变的层状云物理化学模式研究华南春季降水的酸化和对污染物的清除,其结果与外场观测大体一致。
First,the original image is decomposed with wavelet,ratio edge detector is adopted to get the edge direction of manmade targets and Frost filter is performed in the direction,thus efficiently restraining cloud noise and strengthening the manmade target and its edge information at the same time.
首先对原始遥感图像进行小波分解,采用比率-平均边缘检测法检测人造目标的边缘方向,在该方向上进行Frost滤波,有效抑制云层干扰的同时突出了人造目标及其边缘信息;然后进行阈值分割并剔除大块云层,根据区域的平均边缘梯度剔除小块云层,实现了有云遥感图像的舰船目标检测。
