这篇文章的主要特点是研究。本文通过对孟加拉湾和阿拉伯海强气旋风暴场船舶报告资料的分析，得到了该海域强气旋风暴场的合成结构。根据1925 ~ 1954年印度洋强气旋风暴场船舶报告资料，按风暴运动方向将风暴场划分为八分圆，分析了各八分圆内总切向和径向速度随离中心距离的变化。从这些，合成图片给出了总的，切向和径向风场已建成。由此得到了平均曲率场、平均辐散场和平均涡度场，并进行了讨论。还计算了与上述风场有关的降水量，分析了与个别风暴有关的降水量，并与计算值进行了比较。本文的前几段对风暴场和风暴中心的气压分布进行了分析和讨论。还研究了几个有数据的风暴的自由空气温度和海面温度的分布。
The chief feature of the pa per is the study of. the composite structure of the surface wind field in severe cyclonic storms in the Bay of Bengal and the Arabian Sea by analysis of ships' reports received from the storm field, The storm field has been divided into octants, with respect to the direction of movement of the storm and from available ships' reports in the fields of alls3vere cyclonic storms in the Indian Seas during the period 1925-54, the variation of total tangential and radial velocities with distance from centre in each octant analysed. From these, composite pictures giving the total, tangential and radial wind field have been constructed. The mean fields of incurvature, divergence and vorticity have been obtained from the above and discussed. Precipitation associated with the above wind field has also been computed, Rainfall associated with individual storms has also been analysed and compared with computed values. In the initial paragraphs, the distribution of pressure in the storm field and Dear the centre of storm has been analysed and discussed. The distribution of free air temperature and sea surface temperature has also been studied for a few storms for which data were available.
