We carry out the first-ever investigation of four regional varieties of South Asian monsoon low-pressure systems (LPSs) that occur during June-September 1979-2018. We find that long-lived Bay of Bengal (BoB) LPSs are most intense, whereas those over Sri Lanka are least intense. While Arabian LPSs are least frequent, short-lived BoB LPSs are most frequent and bring most precipitation to east India. We also find that tropical intraseasonal variability modulates genesis of these four LPS varieties. </p>
