The Amazon rainforest has been significantly impacted by increased deforestation and a temperature rise of 2.2°C. These factors and climate change disrupt the natural interaction cycle between the forest and the climate, affecting the global moisture flow. In this context, the present study aims to simulate meteorological variables, specifically evapotranspiration and temperature, in the Amazon Basin using the WRF (Weather Research and Forecasting) mesoscale model. The simulation covered the year 2021 with a spatial resolution of 9 km. This allowed for an evaluation of the spatial distribution of temperature and evapotranspiration throughout the year, providing insights into the behavior of these variables in the region. The simulations were satisfactory, underscoring the model's potential to support environmental studies and analyses on the Amazon Basin. It was found that April, October, and November exhibited the highest temperature values, averaging between 36-42 °C. In contrast, the lowest temperatures were recorded in June and July, with average values ranging from 6-18 °C.
