A LAGRANGIAN IDENTIFICATION OF THE MAIN SOURCES OF MOISTURE AFFECTING NORTHEASTERN BRAZIL DURING ITS PRE-RAINY AND RAINY SEASONS.

A Lagrangian identification of the main sources of moisture affecting northeastern Brazil during its pre-rainy and rainy seasons.

This work examines the sources of moisture affecting the semi-arid Brazilian Northeast (NEB) during its pre-rainy and rainy season (JFMAM) through a Lagrangian diagnosis method.The FLEXPART model identifies the humidity contributions to the moisture budget over a region through the continuous computation of changes in the specific humidity along ba

Motion of the dayside polar cap boundary during substorm cycles: I. Observations of pulses in the magnetopause reconnection rate

Using data from the EISCAT (European Incoherent Scatter) VHF radar and DMSP (Defense Meteorological Satellite Program) spacecraft passes, we study the motion of the dayside open-closed field line boundary during two substorm cycles.The satellite data show that the motions of ion and electron temperature boundaries in EISCAT data, as reported by Moe
