Characterization of Extreme Wet‐Bulb Temperature Events in Southern Pakistan

We study extreme wet‐bulb temperature ( T w ) events in a regional hot spot of high T w values in southwest Pakistan's Indus Valley. We focus on the May–June premonsoon months and employ a combination of station data, ERA‐Interim reanalysis, and trajectory calculations to analyze the extreme events. We find that the events are associated with anomalous influx of marine air from the Arabian Sea. The air flows in a shallow layer below 950 hPa and...
