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，

太陽輻射陽光從太陽到達地球表面的過程中，有部分直接穿越大氣層到達地面，稱為太陽直接輻射。其餘的太陽光因被大氣中的空氣分子、水蒸氣及塵粒所散射或反射，而以間接的路徑抵達地面，稱為太陽漫射輻射。總太陽輻射是指所有到達地面的太陽光，即太陽直接輻射及太陽漫射輻射的總和。 Units: W/m2 在晴天，海平面上的最大正常全天空日射約為 \(1000 W/m^{2}\) 太陽能是最充裕的再生能源，
