2. Description of the event
The plots below show the estimates of maximum wind speed and central pressure from different sources (from http://tropic.ssec.wisc.edu/tropic.php# )
During its most intense phase the cyclone passed over a moored research buoy, which measured ~900 hPa.
Below you can find a video of satellite images. Plese note hte gravity wave pattern that radiates out from the cyclone centre.

The animation below show animated sequence of high-resolution visible imagery from a new Chinese civilian geostationary satellite Gao Fen 4 (GF-4). (Provided by Chris Velden.)
The file below includes the TCVitals for Nepartak. Column 10 is the central pressure, column 11 the environment pressure, column 12 the radius to outermost closed isobar (km), column 13 the maximum wind speed (m/s) and column 14 the radius to maximum wind speed (km).
