La región de Transición Cerrado-Amazonía tiene una alta área deforestada en Brasil. Dada la importancia del bosque en el mantenimiento del clima de esta región, evaluamos los patrones de variables micrometeorológicas en áreas boscosas y deforestadas en la región de Transición Cerrado-Amazonía en Mato Grosso, Brasil. Se midió la precipitación, la radiación solar, la temperatura del aire media, mínima y máxima, la humedad relativa del aire, la temperatura del suelo y la velocidad del viento dentro de un bosque (FOR) y en un área deforestada (DEF). La precipitación en la región de estudio presenta un patrón hiperestacional con 95% del volumen en la época de lluvias (octubre a abril), lo que influyó en la estacionalidad de las variables micrometeorológicas. La radiación solar en DEF fue 8 veces mayor que en STR, la temperatura del aire en DEF fue hasta un 11% mayor que en STR, la humedad relativa en FOR fue hasta un 14% mayor que en DEF, la temperatura del suelo en DEF fue de 18 % mayor que en STR y la velocidad del viento en DEF fue 22 veces mayor que en STR. La deforestación influyó significativamente en la estacionalidad y magnitud de las variables micrometeorológicas analizadas.
