Nine simulations are used to predict the meteorology and aeolian activity of the Mars 2020 landing site region. Predicted seasonal variations of pressure and surface and atmospheric temperature generally agree. Minimum and maximum pressure is predicted at \(\text{Ls}\sim 145^{\circ}\) and \(250^{\circ}\), respectively. Maximum and minimum surface and atmospheric temperature are predicted at \(\text{Ls}\sim 180^{\circ}\) and \(270^{\circ}\), respectively; i.e., are warmest at northern fall equinox not summer solstice. Daily pressure cycles vary more between simulations, possibly due to differences in atmospheric dust distributions. Jezero crater sits inside and close to the NW rim of the huge Isidis basin, whose daytime upslope (∼east-southeasterly) and nighttime downslope (∼northwesterly) winds are predicted to dominate except around summer solstice, when the global circulation produces more southerly wind directions. Wind predictions vary hugely, with annual maximum speeds varying from 11 to \(19~\text{ms}^{-1}\) and daily mean wind speeds peaking in the first half of summer for most simulations but in the second half of the year for two. Most simulations predict net annual sand transport toward the WNW, which is generally consistent with aeolian observations, and peak sand fluxes in the first half of summer, with the weakest fluxes around winter solstice due to opposition between the global circulation and daytime upslope winds. However, one simulation predicts transport toward the NW, while another predicts fluxes peaking later and transport toward the WSW. Vortex activity is predicted to peak in summer and dip around winter solstice, and to be greater than at InSight and much greater than in Gale crater.

使用九次模拟来预测 2020 年火星着陆点区域的气象和风沙活动。预测的压力、地表和大气温度的季节变化基本一致。最小和最大压力分别预测为\(\text{Ls}\sim 145^{\circ}\)和\(250^{\circ}\) 。最高和最低表面和大气温度分别预测为\(\text{Ls}\sim 180^{\circ}\)和\(270^{\circ}\) ；即，北方秋分而非夏至最温暖。模拟之间的每日压力循环变化较大，可能是由于大气灰尘分布的差异所致。杰泽罗陨石坑位于巨大的伊西迪斯盆地内部并靠近西北边缘，预计除了夏至前后，该盆地的白天上坡风（～东南风）和夜间下坡风（～西北风）将占主导地位，此时全球环流会产生更多的南风方向。风预测差异很大，年最大风速从 11 到\(19~\text{ms}^{-1}\)不等，对于大多数模拟来说，日平均风速在夏季前半段达到峰值，但在夏季后半段达到峰值。两人的一年。大多数模拟预测每年净沙向西北西方向输送，这与风沙观测结果基本一致，沙通量峰值出现在夏季前半段，由于全球环流和白天上坡风之间的对立，冬至前后通量最弱。然而，一种模拟预测向西北方向的传输，而另一种模拟则预测通量稍后达到峰值并向西南方向传输。 预计涡旋活动将在夏季达到顶峰，并在冬至前后减弱，并且会比洞察号陨石坑更强，也比盖尔陨石坑强得多。
