The troposphere, the lowest 9 miles (15 km) of the Earth's atmosphere, is the layer in which nearly all weather activity takes place. Weather is the result of complex air circulation patterns that can best be described by going from the general to more...

Atmospheric circulation is the large-scale movement of air, and the means (together with the smaller ocean circulation) by which heat is distributed on the surface of the Earth. The large-scale structure of the atmospheric circulation varies from year...

Despite the considerable advances in our ability to observe the global circulation of the atmosphere and to stimulate it numerically, basic features of Earth's climate, for example, storm-track position and many aspects of the tropical climate, remain poorly understood. For improvement and interpretation of...

The relationship between weather and human mortality has been limited to studies centering on one or two meteorological variables, often in connection with a distinct weather "event" such as a heat wave. Recently, the focus began to shift toward a more holistic approach to...

Pollution from Asia is helping generate stronger storms over the North Pacific, according to new research. Changes in the North Pacific storm track could have an impact on weather across the Northern Hemisphere. Satellite measurements have shown an increase in tiny particles generated from coal...
