File:Nancy And Olaf 14 Feb 2005.jpg
Predicting how two powerful storms will interact as they approach each other is a difficult task. Although it is unlikely that the two storms would join together “eye-to-eye,” to form a single massive storm, it is likely they could influence each other's speed and direction. When two storms are within about 1,000 kilometers of each other, their trajectories begin to be influenced by the large-scale atmospheric circulation of the other. For example, if one storm is much stronger than the other, the weaker storm may be tugged off course by the powerful processes that are drawing air into the larger storm. In some cases, this can result in one storm seeming to “orbit” the other. The interaction is called the Fujiwara effect, after a Japanese meteorologist who first described it.
This image was made by combining observations form the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. The part of the image that shows Cyclone Nancy was captured by Aqua MODIS, while the part that shows Olaf was captured by Terra MODIS.(Reusing this file)
