The wind load on a structure is proportional to the square of the wind speed. Extreme wind climate modeling should be requiredfor specifying the design wind speed of structures. Extreme wind speeds for a storm type should be fitted in a suitable probabilitydistribution, from which the design wind speed can be specified for a particular service life of a structure. The methodology, used inIndia for the specification of the design wind speed of existing structures, is fairly old and should be updated. Extreme wind climatein India is mainly influenced by thunderstorms and cyclones. Because thunderstorms and cyclones occur due to different geophysicalreasons, it is necessary to fit extreme events of these two storm types in separate probability distributions, which can be subsequentlycombined to determine the overall non-exceedance probability. For a thunderstorm analysis, the wind speed data for three stationswere considered, namely Kolkata, Lucknow and New Delhi. However, the statistical analysis greatly suffered due to the lowensemble size in Lucknow. Moreover, cyclones very rarely occur; as a result, cyclone modeling for the Bay of Bengal (total eastcoast) was initially considered to obtain a sufficient ensemble size. This paper provides a strategy to determine the specification of thedesign wind speed of structures at a particular location, which is affected by both thunderstorms and cyclones. The motivation of thiswork is to improve the current design methodology as well as the national code of standards to make engineering structures in Indialess vulnerable to damage due to strong winds.
