Cassini taught us much about Titan's hydrology, but there is still much to learn: How frequent will clouds be during northern summer, how will the lakes at Titan's north pole affect cloud formation, will large scale storms be as frequent during northern summer as they were during southern summer? Recently, eagerly-anticipated clouds have begun to be observed for the first time from ground based observations to begin answering such questions. We therefore propose to continue an ongoing campaign to: observe the evolution of Titan's cloud systems and the dynamics that drive them, provide the statistics required to investigate meteorological seasonal variation necessary for understanding Titan's hydrologic cycle, and to discriminate between and further constrain general circulation models [GCMs].
