In this article, we present the major aspects of extra-tropical northern hemisphere climate of North America, Europe and Asia. The Climatic Setting of North America: North America, extending to within 10° of latitude of both the equator and the North Pole, embraces every climatic zone, from tropical rain forest and savanna on the lowlands of Central America to areas of [...]
In this article we will discuss about the major aspects of tropical and southern hemisphere climate. In the tropics, annual temperature ranges are small, Coriolis Effect is minimal, geostrophic flow doesn't occur, less air mass contrast is present, fronts are extremely weak or non-existent, and ridges/troughs appear oriented in opposite directions, as compared with extra-tropical regions. Contrast between Northern and [...]
In this article we will discuss about the external and internal forcing mechanisms of climate change. External Forcing Mechanisms: This section of the article discusses some of the various external forcing mechanisms operating over time scales of 10 years to 109 years. i. Galactic Variations: The orbit of the Solar System about the centre of the Galaxy has been considered [...]
