This paper gives a detailed insight into the performance of ERA5 products, which offers a valuable reference for its probable applicability in the coastal urban areas. Monthly Totals: Yearly Totals: Show My Location Note: Click on map to get the contoured rainfall amount. ERA5 products needs further improvement in the GBA for providing accurate precipitation patterns. We also find that ERA5-Land data with finer spatial resolution fails to deliver any preferable results than ERA5-HRES. Meanwhile, it is challenging for ERA5 products to model precipitation in areas with higher urbanization levels. Due to the different causes of seasonal precipitation as well as the combined influence of coastal effects and topography, the best performance of ERA5 products is found in the southern coastal plains during the wet season and in the northern mountainous vegetation areas during the dry season. Total precipitation for the two months exceeded 15 inches in New London. The results show that ERA5 products generally characterize moderate-intensity rain. Winds with gusts to 75 mph were recorded in the Narragansett Bay area and the. Therefore, we evaluate and compare the ability of two ERA5 products, ERA5-Land and ERA5-HRES, in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) using observations from over 3000 rain gauges in a high-density network during 2018. However, how ERA5 precipitation performs has not been well investigated in urban areas.
some of the extreme weather events in the bay area could be directly attributed to the el nino and la nina phenomena which meteorologists are only beginning to understand. el nino winters typically bring higher than normal rainfall to the san francisco bay region and central coast. ERA5, a state-of-the-art reanalysis product with wide temporal coverage as well as fine spatial and temporal resolution, has greater potential to reproduce precipitation than many other products. 1998’s above normal rainfall totals were not unexpected. A comprehensive understanding of precipitation characteristics, especially that in urban areas, is essential for practical applications in hydrology. Precipitation is an important component of the global water cycle.
