WRF | MPAS | UCM Urban canopy parameters (UCPs) Urban canopy parameters (UCPs) UCPs指的是都市地表參數,包括像地表粗糙度、植被覆蓋、建築密度等指標。這些參數在NWP模型中非常重要,因為它們會影響天氣模型對城市區域的天氣狀況模擬,例如溫度、濕度、風速等。 接下來,我得解釋UCPs如何影響NWP模擬。這可能包括以下幾個面向:地表粗糙度會影響大氣層的摩擦,進而影響風的傳播和速度。植被覆蓋會影響輻射的吸收,改變熱平衡, 2025-02-18 WRF #NWP #HPC #WRF #MPAS #HKO #UCM #LCZs #UCPs
