Climate warming contributes to the record-shattering 2022 Pakistan rainfall

Y. You, M. Ting, et al.

The summer of 2022 brought unprecedented rainfall to Pakistan, driven by human-induced climate change, as revealed by researchers Yujia You, Mingfang Ting, and Michela Biasutti. This study uncovers the intense low-pressure systems and high moisture transport that contributed to record-breaking downpours, raising concerns about the future of extreme weather patterns.

Abstract
The summer of 2022 saw Pakistan experience a series of torrential rainstorms, resulting in record-breaking rainfall (7 sigma). This study investigates the dynamic drivers of these downpours and their connection to human-induced climate change. The analysis reveals that synoptic low-pressure systems initiated the rainfall, exhibiting unprecedented intensity and longevity fueled by historically high cross-equatorial moisture transport over the Arabian Sea. While the trend's exceedance of natural variability remains undetermined, model-based analysis supports its consistency with anthropogenic climate warming, significantly increasing the likelihood of similar extreme events in the future.
