Instrumental measurements of the circulation and thermic regimen of tropical Chapala Lake revealed the surface temperature variations in its eastern part. In all of the cross sections, spatial variations of 3℃ were ordinarily registered over a distance of just 100-300 m. The movements of the internal thermal front in the water body with 2℃ fluctuation were registered at a buoy station. The front’s forepart was accompanied by intensive internal waves in the form of internal KdeV solitons. The front near the buoy station was formed by the movement of the warm water body coming from the eastern shallow part of the lake and stimulated by the morning breeze. 展开更多

利用美国联合台风警报中心(JTWC)发布的北印度洋热带气旋数据、NOAA 0.25°×0.25°逐日OISST资料以及ERA5提供的0.25°×0.25°逐小时的再分析资料分析了阿拉伯海超级气旋风暴“查帕拉”(2015)快速加强过程中... 利用美国联合台风警报中心(JTWC)发布的北印度洋热带气旋数据、NOAA 0.25°×0.25°逐日OISST资料以及ERA5提供的0.25°×0.25°逐小时的再分析资料分析了阿拉伯海超级气旋风暴“查帕拉”(2015)快速加强过程中的环境场特征,结果表明:较常年平均偏暖3.0~3.5℃的暖水区,为“查帕拉”的快速加强提供了水汽和能量条件;“查帕拉”北侧的副热带西风急流和南侧的高空出流通道的建立是其快速加强的重要高空强迫条件,高层辐散风的增强促进质量流出形成强上升运动,这也伴随着旋转风动能的快速增长;在“查帕拉”快速增强时段,高层150 hPa以上存在显著的正位涡异常,高层的正位涡异常能够调整引起低层气旋性环流加强,同时中层400 hPa有显著的正位涡平流输入,正涡度在垂直方向快速增长,300 hPa附近显著增暖,内核区的垂直对流运动达到最强。 展开更多
