Seasonal variation of coastal circulation based on parameter grey estimation and evaluation of residents’ physical exercise behavior

In the past decades, global climate change has greatly changed the natural environment. Due to the lack of measurement data and technical means, there is no consensus on the structure and dynamic mechanism of the b-sea cycle. In this paper, based on ROMs model and grey estimation of parameters, a three-dimensional baroclinic model of thermodynamic coupling in b-ocean region under new background field is established by using high-quality data recently obtained. According to the simulation results and comparative experiments, the seasonal distribution characteristics of b-sea circulation and the water exchange form between b-sea and high seas are analyzed and explained. And many scientific problems of coastal circulation, such as education and mutation mechanism. However, good physical exercise is an important way to improve the physical quality of residents. As the basic requirement of residents’ physical exercise, the community sports environment affects and limits the residents’ physical exercise behavior. Environmental behavior studies show that the relationship between environment and behavior is not directly related to the individual’s response to environmental stimuli. The principle of “applicability” should be emphasized in the construction of sports environment in society. Therefore, the residents’ behavior evaluation of the school sports environment should become an important feedback information in the construction of community sports environment. The purpose of this paper is to analyze the correlation between residents’ sports environment evaluation and sports exercise behavior orientation, and to provide a theoretical basis for improving residents' sports exercise behavior and optimizing and perfecting the sports environment of the community.
