The supercomputers used for NWP calculate the next days’ weather on the basis of current conditions, the laws of physics(物理定律)and various rules of thumb(各种经验法则); doing so at a high resolution calculati eats upons by the trillion with ridiculous ease(轻松得令人发指). Now machine-...
[18]). ARGO data within each bin were averaged, and the differences were computed between observations and models and used to calculate biases and RMSE at each model depth level. The results were then averaged in the vertical to show typical remaining uncertainties after DA. The RMSE and bias...
In addition to these natural causes of hypoxia, anthropogenic drivers, such as eutrophication and warming, have also contributed to hypoxia in the bay [5]. Chesapeake Bay has a surface area of 3500 km2 and a three-month duration of deoxygenated bottom water annually [3]. The volume of ...
