Characteristics Of Dust Devils In Two Pre-Selected Landing Regions Of The Tianwen-1 Mission – Comparing Observations And Predictions By Numerical Model Yemeng Wang , State Key Laboratory Of Lunar And Planetary Sciences, Macau University Of Science And Technology, Macau, Pr China (1909853ese30003@Student.Must.Edu.Mo), Kim-Chiu Chow, State Key Laboratory Of Lunar And Planetary Sciences, Macau University Of Science And Technology, Macau, Pr China, Jing Xiao, State Key Laboratory Of Lunar And Planetary Sciences, Macau University Of Science And Technology, Macau, Pr China Of Maximum Solar Radiation In Their Local Time. This Suggests That The Temporal Variation Of Solar Radiation Due To The Revolution Of Mars Is Primarily Responsible For The Two-Peak Pattern Of Temporal Distribution. The Spatial Distributions Of Dds Both In Za And Zb Are Mainly Related To The Distribution Of Sensible Heat Flux And Surface-To-Air Temperature Difference. In Za, Solar Radiation At Surface Dominates The Spatial Distribution Of Sensible Heat Flux, Thus Causing The Particular Spatial Distribution Of Dlif. In Zb, Our Results Suggest That The Spatial Distribution Of Surfaceto-Air Temperature Difference And Sensible Heat Flux Are Mainly Determined By The Albedo, And So The Resulting Dlif Is Concentrated In The Northwest. The Surrounding Topography Has Little Effect On The Distribution Of The Predicted Dds. In The Southeast Corner Of Zb, The Surface-To-Air Temperature Difference Is Relatively Small Which Is Not Favorable For The Occurrence Of Dds.
