Mesoscale flow modification induced by land-lake surface temperature and roughness differences

Land Surface Roughness Effects on Lake Effect Precipitation

The land use of the Great Lakes region has changed significantly during historical times, and continues to change. As a preliminary step in investigating the overall effect that this might have on climate, attention is focused here on one forcing factor and one effect—land surface roughness length and lake effect precipitation, respectively—that are anticipated to be particularly sensitive piec...

A Study of Mesoscale Atmospheric Circulations Induced by Land Surface Heterogeneity

Mesoscale circulations induced by complex land surface have been investigated using linear stochastic models and a nonlinear numerical model. Random distributions of differential surface heating and variable topography are described in terms of homogeneous random fields. Analytical solutions for the linear atmospheric systems under these random surface forcings have been obtained. The stochasti...

Impact of urban land cover change on land surface temperature

The rapid growth in urban population is seen to create a need for the development of more urban infrastructures. In order to meet this need, natural surfaces such as vegetation are been replaced with non-vegetated surfaces such as asphalt and bricks which has the ability to absorb heat and release it later. This change in land cover is seen to increase the land surface temperature. Previous stu...

An Improvement on Land Surface Temperature Determination by Producing Surface Emissivity Maps

Emissivity mapping of the Earth’s surface is the prerequisite to thermal remote sensing. A precise determinationof a surface's temperature is dependent upon the availability of precise emissivity data for that surface. The presentstudy area is a part of sugarcane plantation fields in the west part of Khuzestan province. In this work, TemperatureEmissivity Separation algorithm (TES) was applied ...
