Effect of solar variability on atmospheric moisture storage

Abstract

The 11-year solar cycle is used as the basis of imparting variability in solar forcing in a General Circulation Model. Using different amplitude solar forcing it was found that the resulting global atmospheric moisture content exhibited a high power in its wavelet spectrum at the 11-year frequency. To identify long term climatic trends, the Earth's atmosphere was conceptualized as a storage reservoir filling and depleting the atmospheric moisture with time. A high required storage implied that the climate ofthat region exhibits larger climate variations leading to a larger moisture scarcity or drought. It was found that regions that had relatively small storage requirements experienced an in..
