Abstract:Floods are one of the most common natural disasters, with a disproportionate impact in developing countries that often lack dense streamflow gauge networks. Accurate and timely warnings are critical for mitigating flood risks, but hydrological simulation models typically must be calibrated to long data records in each watershed. Here we show that artificial intelligence-based forecasting achieves reliability in predicting extreme riverine events in ungauged watersheds at up to a five-day lead time that is similar to or better than the reliability of nowcasts from a current state-of-the-art global modelling system . In addition, we achieve accuracies over five-year return period events that are similar to or better than current accuracies over one-year return period events. This means that artificial intelligence can provide flood warnings earlier and over larger and more impactful events in ungauged basins. The model developed here was incorporated into an operational early warning system that produces publicly available forecasts in real time in over 80 countries. This work highlights a need for increasing the availability of hydrological data to continue to improve global access to reliable flood warnings.
CPU频率之谜:基础、加速、最大加速频率到底是怎么回事?
每次看CPU参数,最抓狂的就是那三行频率:基础频率、加速频和最大加速频率,差得跟三个时代似的,到底该信哪个?其实这三个数没有一个在骗你,它们只是分别对应了三种完全不同的场景,搞清楚背后的逻辑,你就不会再被忽悠了。
从“制造”通胀到激进加息 美式经济治理一错再错
由于本月公布的6月通胀率飙升至高于预期的9.1%并再次刷新40年来最高纪录,外界普遍认为,这次会议会再加息至少75个基点。从各家美媒的观点看,考虑到拜登政府在经济治理上的一错再错,这两个问题都没有乐观答案。
