This is a report of activities of the diverse applications of the numerical weather prediction (NWP) model WRF-ARW implementations developed under a collaborative project between the National Meteorological Service (NMS) and the Naval Hydrographic Service (NHS) of Argentina. A system composed by WPS, WRF-ARW, ARWpost and WPPV3 is running at the NMS on daily basis for the 00 UTC cycle, on a cluster of 5 ML350 HP Proliant nodes. This version is Open MP and distributed implementation. The model’s domain covers South America and the surrounding oceans, with 24 km of spatial resolution and provides 72-hours forecast fields every 3 hs. of precipitation and sea level pressure, maximum CAPE and CIN, RH and TD at 2 m. In addition, 10-meters winds over selected regions of the Argentine coasts and nearby South Atlantic Ocean are produced. Recently, and focused over Argentina, fields such as 700hPa omega and geopotential height, cloud base and 0°C isotherm geopotential height, PBL height and friction velocity, surface visibility, among others, were included for the same cycle. Besides that, there is a broad range of studies underway with the main object of improve the NWP forecasts over the region.
