At Tromsø (69°N; 19°E), ionospheric data from 1952 onwards indicate that the mean altitude of the F2 layer is dropping by 4 km per decade on average. This effect is thought to be attributable to middle atmosphere cooling due to increasing concentrations of anthropogenic carbon dioxide and methane. 相似文献

本文利用西南太平洋地区近12年的热带气旋资料,给出了热带气旋活动频数;同时还运用达尔文区域气象中心发布的部分资料,结合1984至85年度热带气旋活动的特点,从多种不同角度讨论和分析了热带气旋活动多和少的不同环流特征,找出热带气旋发生较为有利的地区。最后还发现该区域热带气旋移动的引导层可能不同于西北太平洋地区,以及一种南太平洋地区热带气旋形成的高低层流场配置。 相似文献

Abstract An analysis of surface observations of cloud characteristics from a selected high‐latitude station, Resolute (N.W.T., Canada), is described. The data set has a high temporal resolution (1 h) and is extensive although here we report only on an analysis of 10 years: 1970–1979, inclusive. The pattern of cloudiness variations is more complex than previous studies of Arctic data have suggested. The predominant reported low‐level cloud type is stratocumulus, not stratus. The generally overcast summer conditions are found to extend over a considerable period when cloud cover is composed of several layers, often of types other than stratus. This observation of multilayering suggests that middle and high cloud layers may occur more frequently than they can be observed. Clearly a more accurate awareness of hidden cloud is important for improving solutions of the planetary radiation budget. The surface radiation budget is found to be strongly affected by the development of the summertime overcast but also exhibits features caused by the mid‐summer break‐up of the lower cloud layer. 相似文献
