摘要

对1877 - 2020年的气旋路径进行了时空强度分析。这些音轨是从以前发表的作品中收集的。以前文章的轨迹被数字化并转换为形状文件,以便在Arc-GIS中进行分析。共使用126条气旋路径,监测气旋的月及季强度及空间变化。这些波动是在30年的时间里进行的,人们认为这是一个特定地点的气候。热带气旋从5月开始袭击孟加拉湾海岸,一直持续到12月。5月和10月是气旋数量最多的月份(每月26个)。从6月到9月,飓风的数量有所下降。在10月和11月,气旋的数量急剧增加。12月的气旋数量大幅下降,1月至3月没有观测到气旋。从1939年到1969年,有记录的气旋数量最多(36个)。在20世纪中后期,气旋的数量较多。孟加拉国沿海地区在最近一段时期(2001-2020年)遭受了历史上最少的气旋。1877年至1907年,西海岸尤其脆弱,1908年至2000年,整个沿海地区都很危险。后季风期(10月至12月)的气旋数量少于季风期(5月至9月)。在季风前季节,有71个气旋袭击,而在季风季节,有53个气旋袭击。

Spatio-temporal variation of cyclone intensity over the coastal region of Bangladesh using 134 years track analysis

The cyclone tracks from 1877 to 2020 were analyzed to detect the spatial and temporal intensity. The tracks were gathered from previously published works. The previous articles' tracks were digitized and converted to shape files for analysis in Arc-GIS. A total 126 cyclone tracks were used to detect monthly and seasonal cyclone intensity and spatial variations. The fluctuations were examined over a 30-year period, which is believed to be the climate of a particular location. Tropical cyclones hit the Bay of Bengal's coast starting in May and lasting until December. In May and October, the number of cyclones is at its peak (26 nos in each month). From June through September, the number of cyclones fell. In October and November, the number of cyclones increased dramatically. The number of cyclones substantially fell in December, and no cyclones were observed from January through March. From 1939 through 1969, the highest number of cyclones (36) was recorded. In the mid- and late-twentieth century, there were a higher number of cyclones. The coastal region of Bangladesh suffered the fewest cyclones in history over the recent era (2001–2020). The western shore was particularly vulnerable from 1877 to 1907, and the entire coastal region was dangerous from 1908 to 2000. In the Post-monsoon (October to December) season, the number of cyclones is lower than in the Monsoon period (May to September). In the pre-monsoon season, 71 cyclones strike, while in the Monsoon season, 53 cyclones strike.

期刊介绍: Tropical Cyclone Research and Review is an international journal focusing on tropical cyclone monitoring, forecasting, and research as well as associated hydrological effects and disaster risk reduction. This journal is edited and published by the ESCAP/WMO Typhoon Committee (TC) and the Shanghai Typhoon Institute of the China Meteorology Administration (STI/CMA). Contributions from all tropical cyclone basins are welcome. Scope of the journal includes: • Reviews of tropical cyclones exhibiting unusual characteristics or behavior or resulting in disastrous impacts on Typhoon Committee Members and other regional WMO bodies • Advances in applied and basic tropical cyclone research or technology to improve tropical cyclone forecasts and warnings • Basic theoretical studies of tropical cyclones • Event reports, compelling images, and topic review reports of tropical cyclones • Impacts, risk assessments, and risk management techniques related to tropical cyclones
