O trabalho correlaciona como as diferentes formas de uso e cobertura do solo interfere nas condições do campo térmico do Campus I da UFPB localizado na cidade de João Pessoa, PB. Para a realização da pesquisa inicialmente foi feito um levantamento bibliográfico a respeito da temática em questão, seguido do reconhecimento da área de estudo e das medições in loco para a coleta dos dados de temperatura e umidade relativa do ar. O experimento de campo foi realizado em 06 pontos representativos do campus durante dois períodos distintos, um chuvoso e o outro seco, de forma a caracterizar as condições do campo térmico local, devido ao adensamento de construções e a presença de arborização. Para o cálculo do índice de conforto térmico foi utilizado o Índice de Thom. Os resultados demonstraram que as diferentes formas de uso e ocupação do solo têm alterado o campo térmico da área em estudo, e gerado uma série de preocupações entre os planejadores desse espaço. Dentre as principais preocupações estão as relacionadas ao crescimento da estrutura da universidade (que se torna inevitável) devido à rápida expansão acadêmica e a diminuição das áreas verdes, que desempenham um papel importante para amenização climática. O Campus Universitário carece de estudos que correlacionem o crescimento das construções com as condições de conforto térmico da população. Em virtude disso, este trabalho tem grande relevância e importância, uma vez que procura articular os estudos na área de climatologia urbana ao planejamento e ordenamento territorial urbano.

Urban Climate: Characterization of Thermal Field and its Relations with the Different Forms of Soil Usage and Occupation in the Central Campus of UFPB
ABSTRACT
The work seeks to correlate how different forms of use and land cover interfere under conditions of thermal field of UFPB Campus I located in the city of João Pessoa-PB. To carry out the search was initially made a bibliographic survey regarding the subject in question, followed by the recognition of the study area and spot measurements for the collection of data of temperature and relative humidity. Field experiment was conducted on 06 representative points of campus during two distinct periods, a rainy and dryin order to characterize the conditions of the local thermal field, due to the densification of constructions and the presence of af forestation. For the calculation of thermal comfort index was used the index of Thom. The results demonstrated that the different forms of soil usage and occupation have changed the thermal field of the área under study, and generated a number of concerns among the planners of this space. Among the main concerns are related to the growth of the University's structure (that becomes unavoidable) due to rapid academic expansion and decline of Green areas, which play an important role for climate thawing. The Campus lacks studies that correlate the growth of buildings with thermal comfort conditions of the population. As a result, this work has great relevance and importance, since it seeks to articulate the studies in the area of urban climatology to urban planning and regional planning.
