Interactions Among Atmosphere, Soil, and Vegetation

Abstract

Fundamental equations of the atmosphere-land surface interactions are presented. Based upon those equations, we have developed the atmospheric and land-surface models at Purdue University. The numerical results show the models are capable of reproducing the major features of observations. Models also help us to understand the physical processes involved in atmosphere, soil and vegetation. However, it is obvious that more observational data should be collected and more scientists in different disciplines should work together to study the mechanisms at and near the land surface, which is crucial before a comprehensive model can be developed to predict the change of climate, water resources, and ecology accurately. 從空氣、土壤及植物之基本流力方程式，我們在普度大學發展一套「空氣、土壤及值物交互作用」的數學模式。這個模式能夠模擬地面及地表附近所觀測的一些重要現象，同時幫助我們瞭解其中的物理現象。然而，很明顯地，我們仍需要收集更多的觀測資料，並鼓勵更多不同領域的科學家共同來探討這些物理機制，才可能發展一套完整的數值模式來預測為來氣候、水資源及生態的變化。
