SMN Hi-Res Weather Forecast over Argentina

The Servicio Meteorológico Nacional de Argentina (SMN-Arg), the National Meteorological Service of Argentina, shares its deterministic forecasts generated with WRF 4.0 (Weather and Research Forecasting) initialized at 00 and 12 UTC every day. <br/> <br/> This forecast includes some key hourly surface variables –2 m temperature, 2 m relative humidity, 10 m wind magnitude and direction, and precipitation–, along with other daily variables, minimum and maximum temperature. <br/> <br/> The forecast covers Argentina, Chile, Uruguay, Paraguay and parts of Bolivia and Brazil in a Lambert conformal projection, with 4 km horizontal resolution. The maximum lead time is 72 hours. <br/> <br/> Forecasts are initialized with the NCEP-NOAA Global Forecast Systems analysis and forecasts (<a href="https://www.ncei.noaa.gov/products/weather-climate-models/global-forecast">GFS</a>).

阿根廷国家气象服务局（Servicio Meteorológico Nacional de Argentina，简称SMN-Arg）共享其使用WRF 4.0（天气与研究预报）模型生成的确定性预报，该模型每日以00时和12时UTC为初始时间进行初始化。该预报包含若干关键小时地面变量，包括-2米温度、2米相对湿度、10米风速及风向，以及降水量，此外还包含其他每日变量，如最低温度和最高温度。预报范围覆盖阿根廷、智利、乌拉圭、巴拉圭以及玻利维亚和巴西的部分地区，采用拉默特正形投影，水平分辨率为4公里。预报的最长预测时效为72小时。预报初始化采用美国国家环境预报中心（NCEP）- 美国国家海洋和大气管理局（NOAA）全球预报系统分析及预报（Global Forecast Systems，简称GFS）。
