Meteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology compose the interdisciplinary field of hydrometeorology. Interactions between Earth's atmosphere and the oceans are part of coupled oceanatmosphere studies. Meteorology has application in many diverse fields such as the military, energy production, transport, agriculture and construction. Fundamental science of the tropical atmosphere and synthesizes the tremendous increase in our knowledge of tropical meteorology during the past two decades. In that same period, great advances also occurred in learning technologies; allowing students to learn through interactivity and access to real data.
