Due to climate change, extreme weather events such as heavy rainfall are becoming a common occurrence. In a tropical setting, rain can be highly localized and changes quickly. Rainfall tends to appear and disappear quickly within an hour causing flash floods in urban areas. This technology relates to a novel smart rainfall prediction system utilizing data from multiple X- band rainfall monitoring radars. The X- band radar scans the sky for rain, feeding data into the system every 2 minutes to create an accurate map of the real-time rainfall intensity though the use of a nowcast model. This allows the relevant municipal authorities to improve on existing flood management measures and react quickly in case of flash floods. The technology owner is currently looking to license the technology to logistic companies and city governments.
