Proton temperature anisotropies between the directions parallel andperpendicular to the mean magnetic field are usually observed in the solar windplasma. Here, we employ a high-resolution hybrid particle-in-cell simulation inorder to investigate the relation between spatial properties of the protontemperature and the peaks in the current density and in the flow vorticity. Ourresults indicate that, although regions where the proton temperature isenhanced and temperature anisotropies are larger correspond approximately toregions where many thin current sheets form, no firm quantitative evidencesupports the idea of a direct causality between the two phenomena. On the otherhand, quite a clear correlation between the behavior of the proton temperatureand the out-of-plane vorticity is obtained.
