TEMPERATURE FLUCTUATION AND RELATIVE HUMIDITY IN RECIFE - PE, BRAZIL

Abstract

The objective is to study the variability of temperatures and relative humidity of the air, comparing the periods of 1962-1990 and 1991-2016 with the averages of 1931-2016 and 1962-2016 respectively, seeking to quantify climate change and identify the influence of large-scale climate events El Niño and La Niña, aiming to contribute to the managers responsible for urban planning and improving the quality of life of inhabitants and the ecosystem. Data on air temperature and relative humidity, provided by the National Institute of Meteorology (INMET), were used. Basic statistical parameters were calculated such as: mean, standard deviation, coefficient of variance, variations of annual anomalies in order to identify buoyancy in the data and the influence of extreme events. The city of Recife suffered from the disordered growth, without specific planning patterns in urbanization that caused variations in the microclimate of urbis, causing thermal discomfort and reduction of the quality of life of its inhabitants. There is an intense flow of automotive vehicles and people throughout the day due to activities related to work, commerce and services, in addition to the concentration of several buildings, waterproofed areas as well as buildings hindering the circulation of local air. It is suggested an increase in green areas interneighborhoods from the afforestation that has been shown to be an alternative for improving the quality of life in urban spaces.
