4.1 Deterministic forecast metrics comparison 本小节比较了FuXi、ECMWF HRES、GrahpCast(目前最先进的ML天气预报模型)、ECMWF EM和FuXi EM在确定性指标上的预测性能。图2显示了FuXi、ECMWF HRES和GraphCast对于4种地面变量(MSL、T2M、U10和V10)以及4种高空变量(Z500、T500、U500和V500,500 hPa气压层)的全球平均纬...
Comparison of three weather prediction models with buoy and aircraft measurements under cyclone conditions in Fram Straitdoi:10.1111/j.1600-0870.2009.00460.xOperational model analyses of the European Centre for Medium-Range Weather Forecast (ECMWF), the German Weather Service (DWD) and the Norwegian ...
As we analyze the numbers and forecast the future of the Weather market, it becomes evident that in China has a significant role to play. With its large population and growing digital landscape, the Weather market in China holds immense potential for revenue growth and technological advancements....
In a system-level comparison, FourCastNet requires 0.28 s for inferring a 24-hour forecast on a Tesla-A100 GPU (312 teraFLOPS), whereas Pangu-Weather needs 1.4 s on a Tesla-V100 GPU (120 teraFLOPS). Taking GPU performance into consideration, Pangu-Weather is about 50% slower ...
ECMWF added a range of data-driven AI predictive models as part of its platform solution. Pangu forecast maps are displayed on the website in six dimensions: mean sea level atmospheric pressure and 850 hPa wind speed, 500 hPa altitude and 850 hPa temperature, mean sea level atmospheric pressur...
(HFIP), by providing a moving nest within global models as part of engineering efforts of the Hurricane Analysis and Forecasting System (HAFS), by improving both Storm Surge forecasting and National Hurricane Center (NHC) Forecast Techniques, and by deployment of next generation in-situ measurement...
Before Pangu, forecast execution had been increasing by about one day per decade (according to the World Meteorological Organization, or WMO), which can be attributed to the high computational cost of running a forecast with standard NWP systems. ML models are poised to revolutionize weather ...
The Weather Channel and weather.com provide a national and local weather forecast for cities, as well as weather radar, report and hurricane coverage
The analysis step combines observation and forecast to describe the current state in a better way than the forecast. This obtained value is the initial point for an expected value for a later time t1. (right) Comparison between radiosonde data and GDAS data at the Pierre Auger Observatory. ...
