This study presents an analysis of the occurrence of Low Level Jets (LLJs) in a grassland area in the southwestern Amazon. Using the wind vertical profile data obtained by atmospheric radiosonde, it was observed that about 60% of total analyzed profiles showed LLJs. This percentage is higher than found in several studies in the Amazon and is linked to the LLJs selection criteria used in this work. Another interesting result is the tendency of weak LLJs is associated with lower heights, whereas strong LLJs preferentially develop in greater heights. This result suggests that different mechanisms may have generated the LLJs of different intensities.
