摘要

摘要 SLAV 是一种地球大气数学模型，可根据当前天气条件预测未来天气。本文介绍并评估了基于能量平衡的数值算法，以将 LAKE 模型应用到 SLAV 中。LAKE 是一个扩展的一维湖泊模型，已在一些气候条件截然不同的湖泊中以独立模式进行了热和冰机制测试。在长达 4 个月的准备时间内进行的数值模拟以及在相同准备时间内对天气异常进行的回顾性预测所获得的结果表明，所开发的方法适用于再现湖泊-大气耦合。

Numerical Aspects and Implementation of LAKE Scheme into a Global Atmospheric Model SLAV

Abstract

SLAV is a mathematical model of the Earth’s atmosphere that predicts weather in future based on current weather conditions. This paper describes and evaluates the numerical algorithm based on the energy balance for implementing the LAKE model into SLAV. LAKE is an extended one-dimensional model of lake that has been tested in respect to thermal and ice regime at a number of lakes in contrasting climate conditions in a standalone mode. The results obtained from numerical simulations for lead times up to 4 month and retrospective forecasts of weather anomalies with the same lead time indicate the applicability of the developed approach to reproduce lake-atmosphere coupling.
