We're planning to retire the Community Data Portal (CDP) after nearly 15 years of service. The most active datasets will be migrated to the Climate Data Gateway website. We tentatively plan to shutdown the CDP service by Jan 1, 2018. Please contact us with questions or concerns.

Summary This simulation marks the first time a cloud-resolving simulation has been able to reproduce the formation of a tropical cyclone, given only information about atmospheric conditions on a scale much larger than that of the cyclone.n a key step toward improving the prediction of hurricanes, NCAR scientists have reproduced in a computer model the fine-scale structure that drives the birth and strengthening of tropical cyclones. The simulation marks the first time a cloud-resolving simulation has been able to reproduce the formation of a tropical cyclone, given only information about atmospheric conditions on a scale much larger than that of the cyclone. To resolve the eyewall and precipitation bands within a tropical cyclone, the MM5 model was used. With a horizontal distance as small as 1.2 km between the model's computation points, MM5 is one of the world's highest-resolution models for reproducing storm-scale weather across a large area. Diana was chosen because of ample surface data and because a well-defined nontropical low preceded its formation.
