Location of Nepal • South Asian landlocked country with fascinating topography and climate. • It lies between 26022’to30027’N lat and 84004’to 88012’E long. • Area: 1,41,741 sq km. • Highest elevation: 8848 m • Lowest Elevation: 64 m

Physiographic Regions based on Topography and 15 Synoptic Stations • Terai (60-200)M ,17%, • Churia, ( Siwalik Range) (200-1500)M • Middle Mountain (Mahabharat range) (1200-2500)M,68% • High Mountain (2500-4000)M • High Himalayas (4000-8848)M 15%
Forecasting Method • Persistence method (synoptical, climatological) • Model products by WRF • (NWP ECMWF, IMD Model Charts, NCEP’s Climate Prediction Center (CPC) etc.) • Site-specific forecasts for surface weather parameters (EPSgrams) for specified locations (up to 10 stations of country) • Satellite images are used
10 locations (synoptic stations) for which the ECMWF would provide EPSgrams for Nepal
Dissemination systems • DHM is issuing on daily basis public weather bulletins twice a day to the public through internet.(mfd.gov.np) • Disseminate the special bulletin to higher authorities by using fax, phone, mobile phones etc. if required. • Through media (Both print and e-media) • National Disaster Management • NGO and INGO
Future Plan • Installation of AWS in all synoptic stations under SAARC_STORM project. • One Doppler Weather Radar probably next year • Two GPS Sonde Stations • 16 telemetry rainfall stations will be installed in model basin. • Pilot Program for Climate Resilience (PPCR) is going to commence next year to modernized and development in existing system.
