Abstract

Short-range forecasts of variations in the level of the Sea of Azov with a lead time of 48 hours are computed with a three-dimensional hydrodynamic model (a grid spacing is 0.5 nautical miles) twice a day at 00:00 and 12:00 using wind speed and air pressure fields on the sea surface from the COSMO model (a grid spacing is 7 km). To eliminate differences between the sea-level simulations and observations, a correction is introduced, that is defined as a difference in the mean level of the Sea of Azov according to observations at coastal stations and model simulations. After introducing the correction of the mean level of the Sea of Azov in the automatic mode, the operational model simulates not only surges but also seasonal sea level variations, for example, a gradual sea level drop in May–December 2020.

基于海岸台站观测的季改亚速海平面短期变化业务预报

摘要

使用三维水动力模型（网格间距为 0.5 海里）每天两次在 00:00 和 12:00 计算提前 48 小时的亚速海水位变化的短期预报使用来自COSMO模型的海面风速和气压场（网格间距为7 km）。为了消除海平面模拟和观测之间的差异，引入了一个修正，即根据沿海站的观测和模型模拟，定义为亚速海平均水平的差异。在自动模式下引入亚速海平均水位修正后，业务模型不仅模拟了潮汐，还模拟了季节性海平面变化，例如 2020 年 5 月至 12 月的海平面逐渐下降。
