The most profound deformational event involving the interaction of lithospheric plates is a collision between continents; for example, the collision of the Indian continent with the Eurasian continent, which began in the Eocene. This continuing collision has produced intracontinental thrust sheets responsible for the highest mountains in the world. Mount Everest, the Annapurna Range, and the rest ... Full description.

Much like El Nino, the North Atlantic Oscillation (NAO) varies in a rhythmic pattern from decade to decade. The NAO is the relationship between a high-pressure system over the Azores Islands and a low-pressure system over Iceland. This site uses text, photographs, and maps to explain what the NAO is and how it affects weather in Europe, the United States, and as far away as the Middle East. Full description.

This article describes the use of satellite remote sensing to examine supercell thunderstorms with the intent of predicting when or if they are likely to produce tornadoes. During the afternoon and evening of May 3, 1999, a series of supercell thunderstorms produced large, destructive tornadoes concentrated in central Oklahoma. During this outbreak, the NASA Tropical Rainfall Measuring Mission (TRMM) ... Full description.
