Impact of meso-net observations on short-term prediction of intense weather systems during PRWONAM: Part I-On wind variations

► Mesoscale modeling of observed wind profiles over the southern peninsular India. ► Meso-net data assimilated. Wind predictions at optimum horizontal resolution of 3 km. ► A bias of 3.84 m s−1 (zero bias) exists in predictions for spring (monsoon) season. ► The instantaneous wind prediction is 83% in ±5 m s−1 error bound for the spring. ► The prediction is 71% within the error bound during the monsoon season.
