Abstract

According to an urban canopy model establishment method based on tropical island climate characteristics and provided by the invention, adjacent regions are linked together, a plurality of streets with finite lengths in the regions and mutual influence are realized, and the net radiant heat flux tropical island urban canopy model has the characteristics of high net radiant heat flux and high net radiant heat flux. In consideration of strong solar radiation and high-temperature and high-humidity climate characteristics of tropical cities and influence of monsoon throughout the year on island cities, a method for processing long-wave radiation flux, short-wave radiation flux, sensible heat and latent heat flux, street canyon wind speed, heat storage flux, man-made heat flux and horizontal heat flux is improved on the basis of an urban canopy model; and the suitability for researching the heat island effect of the tropical sea island type city is higher.

Description

technical field

[0001] The invention relates to the field of urban canopy, in particular to a method for establishing an urban canopy model based on climate characteristics of tropical islands. Background technique

[0002] In the current research process on the urban heat island effect, the classic urban canopy model is generally used when modeling urban street valleys. However, due to the huge differences in the longitude and latitude of cities, local climate characteristics, landforms, and land use characteristics, the parameterization methods in the urban canopy model are very different. The treatment method of "ignoring" is insufficient for studying the heat island effect of "tropical island" cities, because tropical islands have the characteristics of strong horizontal ventilation brought about by strong winds all year round. Contents of the invention

[0003] In view of the above problems, the present invention is proposed to provide a method for establishing an ur...
