Understanding the spatial and temporal variation of precipitation is important to identify its driving potential extreme events that impact on socio-economic conditions at national provincial scales. This study presents related in scale using 143 rain-gauge stations across Nepal during 2001–2016. The results show differences distribution, with highest Province 4 (Bagmati) lowest 6 (Karnali). decreasing trend scale, expect for 6. distribution shows wettest (Lumle) driest (Manang Mustang) areas country located within same 4. seasonal cycle reveals longer period monsoon Provinces 1 4; meanwhile, a shorter was observed 7 (Farwestern). Heavy (R10mm) (R25mm) were higher those provinces more extended vice-versa. result further number Consecutive Dry Day (CCD) spells all than Wet (CWD) spells. time-series (R10mm, R25mm, CDD CWD) an inter-annual seven 2001-2016. wet dry reversed lying eastern western parts country. helps update upgrade our understanding variability extremities over different Nepal, which can assist government disaster management.
