MPAS-A aquaplanet simulation with convection-permitting resolution and off-equatorial SST maximum

This dataset includes model output from an aquaplanet simulation using the Model for Prediction Across Scales-Atmosphere (MPAS-A). The aquaplanet simulation was produced by prescribing a zonally symmetric sea-surface temperature profile and by removing land, sea-ice, and the seasonal cycle from the model. Unlike previous aquaplanet simulations (https://doi.org/10.5065/cam1-v353), this simulation had an SST profile with an off-equator maximum at 10N to allow for the formation of tropical cyclones. A variable resolution mesh was used with 3-km cell spacing between 10S and 30N, transitioning to 15-km cell spacing elsewhere. The simulation was integrated for 160 days, but the first 30 days were discarded for model spinup. This dataset contains post processed output interpolated to a r1440x720 fixed grid with approximate grid spacing of 0.25 deg.

本数据集收录了基于尺度预测模型-大气（Model for Prediction Across Scales-Atmosphere，简称MPAS-A）进行的模拟海洋行星的模型输出。该模拟海洋行星通过设定纬向对称的海面温度分布并去除陆地、海冰及季节性循环，得以生成。与先前进行的海洋行星模拟（https://doi.org/10.5065/cam1-v353）不同，此次模拟的海面温度分布呈现出非赤道最大值位于10N的特点，从而为热带气旋的形成提供了条件。在10S至30N之间，模拟采用了3公里分辨率的网格，其他区域则过渡至15公里分辨率网格。该模拟历时160天，但前30天因模型启动过程而被舍弃。本数据集包含了对处理后的输出进行插值，以r1440x720固定网格形式呈现，其网格间距约为0.25度。
