全球为何如此之热?北半球同时出现4个“热穹顶”,地球或迎12万年来最热的一个月!
近日,全球多地气候系统纷纷亮起了红灯,至少三个大洲的高温刷新历史纪录。继出现全球有记录以来最热的6月及10万年以来最热一周后,地球再次迎来了“最热15天”和“12万年来最热一个月”的历史纪录。

《海洋预报》| 两个相似路径台风途经鲁西南时降水差异的成因分析
Abstract:Based on the conventional observation data and FNL reanalysis data, the causes of the precipitation difference between typhoon “Yagi” and “Rumbia” passing through southwest of Shandong Province with similar tracks are analyzed in this paper. The results show that the difference in circulation pattern is the main reason for the precipitation difference between the two typhoons. Typhoon “Yagi” is in the equal pressure field on 500 hPa, and the precipitation is mainly from the typhoon itself, which is located at the top of the typhoon. Typhoon “Rumbia” is merged into the upper trough, and the precipitation is mainly frontal precipitation, which is located on the right-front side of the typhoon direction. Moreover, the water vapor sources as well as the locations of vapor convergence of the two typhoons are different. The locations of positive vorticity advection on 500 hPa and the wind shear on 925 hPa have a good indication of the rainfall area, and the barotropic structure with warm center and weaker environmental vertical wind shear of typhoon “Yagi” is more favorable for the formation of precipitation nearby compared to typhoon “Rumbia” with stronger environmental vertical wind shear and baroclinic structure induced by front. The mesoscale diagnosis analysis of the two typhoons shows that the non-geostrophic wet Q-vector and the vertical helicity can be used to diagnose the rainfall area. In addition, the moist potential vortex shows that the wet barotropic term less than 0 is only a necessary condition for the occurrence of precipitation and not a factor determining the location of rainfall, while the wet baroclinic term is a better indicator for the location and intensity of rainfall.预计后天,东海东南部将生成新的大浪区,浪高2到2.8米并移动至日本以南洋面。
中国为什么地震频发?——挤出来的西部地震和拉出来的东部地震
中国,是一个饱受地震蹂躏的国度。20世纪以来,全世界死亡人数前十位的大地震里,有三场发生在中国,它们分别是1920年甘肃海原(现划归宁夏)大地震,死亡27.3万人;1976年河北唐山大地震,死亡24.3万人;2008年四川汶川大地震,死亡及失踪8.7万余人。
惠州有钱人都住在哪里?
以前,我们总以为富人更喜欢住在远郊,深山野林里,单门独户一座别墅,似乎具有很强的私密性。2012年,一曲《江南style》从韩国火到了中国大江南北,也因此让中国全民认识了韩国汉江以南的富人区——江南区。江南区是韩国首都首尔的一个行政区,位于汉江以南。全区面积39.
规模125千米,日本南海海沟隐藏了巨型结构!恐将引发超级地震?
相信很多朋友都应该看过《日本沉没》这部经典电影,尽管这是一部日本电影,但看着日本沉入太平洋总是有种莫名的兴奋,所以还是非常值得一看的!
