常规的思维,如前所述,就是比较等压面的气压Plevel和该位置正下方地面的地面气压Psp(Surface Pressure),如果等压面气压小于地面气压(即Plevel<Psfc),则该等压面位于地面之上,该气压层的气象要素(比如温度,风速)有实际意义,若该等压面位于地面之下,则该气压层的气象要素没有实际意义。 但是,实际工作中,一般用的是海平...

Pressure tidesTemperatureHumidityWindsThe diurnal cycle is a prominent feature of Earth's weather and climate. Partly due to lack of sub-daily data, our understanding of the diurnal cycle is incomplete. This study analyzes 3-hourly surface observations and ERA5 hourly data to evaluate ERA5's ...

ERA5 DAILY provides aggregated values for each day for seven ERA5 climate reanalysis parameters: 2m air temperature, 2m dewpoint temperature, total precipitation, mean sea level pressure, surface pressure, 10m u-component of wind and 10m v-component of wind. Additionally, daily minimum and maximum...
