Study on heat island effect in Sheyang port economic development zone
摘要
Abstract
The heat island phenomenon of Sheyang port economic development zone was studied by using observational data,remote sensing data and WRF-LES model.Observation data shows that since 2014,the temperature in Sheyang port economic development zone has continued to rise,but due to its geographical location,the increase is not as strong as in the surrounding areas.Through further analysis on remote sensing data,it was found that from 2013 to 2022,due to the expansion of urban building area and the reduction of green area,the heat island effect of Sheyang development zone has been enhanced over time.Finally,based on the output results of the WRF-LES model,the energy changes of the underlying surface and surrounding farmland in the Sheyang development zone were analyzed.Sensible heat flux is the main source of daytime temperature,and soil heat flux mainly affects nighttime temperature.Therefore,during the daytime and evening of the spring and autumn seasons,the temperature of the underlying surface in the development zone is significantly higher than that of the farmland,and the temperature difference in other seasons is not significant.Autumn is the month with the most obvious urban heat island phenomenon in the Sheyang port economic development zone.关键词
