Study characterizes the precipitation events that can occur during the dry quarter in the region of the Alcantara Launch Center. Data collected over 37 years was used to confirm their average features and obtain the large-scale organization of the convective activity during higher precipitation events. The results presented could be helpful for short-term weather forecasting during launching missions. … Read More →

The present article details an experiment using a scale model of the Launching Pad Area in a subsonic wind tunnel, using the particle image velocimetry (PIV) technique to collect results in different wind flow incidence configurations. The results identify the peculiarities of the region’s typical wind action, and its effects on launch structures and operations on one of the world’s most strategically located space launching bases. … Read More →
