相对湿度会达到100%吗

我利用ERA5-reanalysis的数据绘制相对湿度图，但是显示有些区域相对湿度超过100%，甚至达到110%，这个正常吗？还是说相对湿度数据要先做一些处理才能用

参考EC论坛回复：https://forum.ecmwf.int/t/relative-humidity-data-exceeds-100/1579
ERA5 relative humidity data on pressure levels above 500 hPa can exceeds 100%. This could be due to supersaturation with respect to ice at cold temperatures.

See the ERA5 IFS documentation (CY41R2), Part IV Physical processes, Chapter 7- Clouds and large-scale precipitation, for more information:https://www.ecmwf.int/en/publications/ifs-documentation
