In the atmosphere-surface interaction, the condition of the earth surface controls the atmospheric surface layer and sub-surface soil (water) layer. However, most of the previous studies mainly deal with stationary process, which is considered as easy to match with theoretical models. While, in the real atmospheric condition, non-stationary processes are most dominant and should be studied more detail to improve climatic model prediction. In the present study, we have observed a variety of non-stationary processes, including solar radiation, precipitation, cloudiness and so forth. The surface response can be variable with surface condition, such as soil, water or plant canopies.A long term observations were carried out over various surfaces and systematic response characteristics were realized experimentally. Based on these experimental results, we have configured surface models to be applied various local circulation models. These scientific results were reported and published in many academic societies or journals.Further studied should be continued to improve surface models including more complicated processes.

在大气-地表相互作用中，地球表面的状况控制着大气表层和地下土（水）层。然而，以往的研究大多主要针对平稳过程，被认为易于与理论模型匹配。然而，在真实的大气条件下，非平稳过程占主导地位，应该进行更详细的研究，以改进气候模型的预测。在本研究中，我们观察到了多种非平稳过程，包括太阳辐射、降水、云量等。表面响应可以随表面条件而变化，例如土壤、水或植物冠层。对各种表面进行了长期观测，并通过实验实现了系统响应特性。基于这些实验结果，我们配置了表面模型以应用各种局部环流模型。这些科学成果在许多学术团体或期刊上都有报道和发表。应继续进一步研究以改进包括更复杂过程的表面模型。
