我们开发了一个简单的物理模型ALAKE，适合于估计一个新湖泊对其附近温度特征的影响。该模型由包含自由参数的简单物理方程组成，这些参数的值是确定的，因此ALAKE输出接近“真实”值。为了确定“真实”值，我们使用了水平分辨率为333米的COSMO模型。ALAKE是为平坦地形开发的，使用相对容易获取的数据。这些条件，即所列数据的可用性和近似平坦的地形，在计划应用ALAKE的Podkrusnohorske山谷都得到了满足。对COSMO和ALAKE输出的比较表明，两者的输出具有相似的基本特征，尽管它们在单个项上可能有所不同，但其气候特征是相似的，这表明ALAKE模式可以估计湖泊对其附近温度特征的影响。
We developed ALAKE, a simple physical model suitable for estimating the influence of a new lake on temperature characteristics in its vicinity. The model consists of straightforward physical equations containing free parameters whose values were determined so that ALAKE outputs approached the “true” values. To determine the “true” values, we used the COSMO model, which we applied with a horizontal resolution of 333 m. ALAKE was developed for flat terrain and uses relatively easily accessible data. These conditions, i.e., the availability of listed data and an approximately flat terrain, are fulfilled in Podkrusnohorske Valley, where the application of ALAKE is planned. The comparison of the COSMO and ALAKE outputs showed that the outputs have similar basic features and although they may differ for single terms their climatological characteristics are similar, suggesting that the ALAKE model can estimate the influence of a lake on the temperature characteristics in its vicinity.
