查询词典 topography

The wind fields andtemperature fields data provided by "D files" from 14 surface observationstations around Beijing area are used to produce the mean wind fields and the meantemperature fields over Beijing area in summer and winter. Such results are gotten:(1)Due to the unique topography the wind of Beijing area during the day time is southernanabatic wind and in the night is northern katabatic wind in summer.
