            "description": "This visualization won Honorable Mention in the National Science Foundation's Science and Engineering Visualization Challenge in September 2007. It was also shown during the SIGGRAPH 2008 Computer Animation Festival in Los Angeles, CA. 'Towers in the Tempest' is a 4.5 minute narrated animation that explains recent scientific insights into how hurricanes intensify. This intensification can be caused by a phenomenon called a 'hot tower'. For the first time, research meteorologists have run complex simulations using a very fine temporal resolution of 3 minutes. Combining this simulation data with satellite observations enables detailed study of 'hot towers'. The science of 'hot towers' is described using: observed hurricane data from a satellite, descriptive illustrations, and volumetric visualizations of simulation data. The first section of the animation shows actual data from Hurricane Bonnie observed by NASA's Tropical Rainfall Measuring Mission (TRMM) spacecraft. Three dimensional precipitation radar data reveal a strong 'hot tower' in Hurricane Bonnie's internal structure. The second section uses illustrations to show the dynamics of a hurricane and the formation of 'hot towers'. 'Hot towers' are formed as air spirals inward towards the eye and is forced rapidly upwards, accelerating the movement of energy into high altitude clouds. The third section shows these processes using volumetric cloud, wind, and vorticity data from a supercomputer simulation of Hurricane Bonnie. Vertical wind speed data highlights a 'hot tower'. Arrows representing the wind field move rapidly up into the 'hot tower, boosting the energy and intensifying the hurricane. Combining satellite observations with super-computer simulations provides a powerful tool for studying Earth's complex systems. The complete script is available here . The storyboard is available here . There is also a movie of storyboard drawings with narration below. || ",

            "title": "A Hurricane Model",
            "description": "NASA scientists use the computer modeling field including the NCAR Mesoscale Model Version 5 (MM5) model to study the winds and updrafts near the hurricane's eye.  An updraft is the vertical upward movement of air inside of a storm.  This research  focuses on the processes that impact the formation, intensification, movement, structure, and precipitation organization of hurricanes.  An MM5 simulation of Hurricane Bonnie (1998) suggests that the timing and location of individual updrafts that produce the rainfall (often concentrated on very small-scales) are controlled by intense, small-scale regions of rapidly swirling flow in the eyewall.The winds in hurricanes are often described in terms of radial (in toward the center or out away from it) and tangential (the swirling flow around a hurricane) winds. By looking at the urad field, one can see where the main inflow and outflow regions of the storm are, which can be important for a variety of reasons.  Eyewall mesovortices are small scale rotational features found in the eyewalls of intense tropical cyclones.  In these vortices, wind speed can be up to 10% higher than in the rest of the eyewall. Eyewall mesovortices are a significant factor in the formation of tornadoes after tropical cyclone landfall. Mesovortices can spawn rotation in individual thunderstorms (a mesocyclone), which leads to tornadic activity. At landfall, friction is generated between the circulation of the tropical cyclone and land. This can allow the mesovortices to descend to the surface, causing large outbreaks of tornadoes. || ",
