Abstract

Cumulative precipitation in northern India in June 2013 was a century-scale event, and evidence for increased probability in the present climate compared to the preindustrial climate was equivocal. The upper- and lower-level synoptic conditions in early and mid-June supported the anomalously early monsoon-like circulation and excessive precipitation in northern India. This upper-level blocking pattern guided mid-to-high-latitude troughs southward, thereby facilitating the advection of relatively cold, dry, high-potential-vorticity air to the upper levels of the atmosphere over northern India.
