Operational SeaWinds on QuikSCAT data can be enhanced to yield a 2.5 km ultra-high resolution (UHR) wind product, which can be used to help estimate tropical cyclone (TC) characteristics such as TC center and wind radii. This paper provides the results of two studies in which the QuikSCAT UHR wind product's effectiveness in estimating these TC characteristics is evaluated. First, a comparison is made between an analyst's choice of center location based on UHR images and interpolated best track… 
Tropical Cyclone Center Automatic Determination Model Based on HY-2 and QuikSCAT Wind Vector Products
A new method for the automatic determination of the center of TCs using HY-2 and Quick Scatterometer wind vector products and the results show that the accuracy of the TCCAD method is close to that of the human expert method for most TCs and the standard deviation is much smaller than that in thehuman expert method.

A simplified hurricane model is developed to provide prior information to be used in maximum a posteriori probability estimation of ocean winds, which reduces the variability of the wind speed and direction estimates, although high wind speeds still tend to be underestimated.
A QuikSCAT climatology of tropical cyclone size
QuikSCAT data of near‐surface wind vectors for the years 1999–2008 are used to create a climatology of tropical cyclone (TC) size, defined as the radius of vanishing winds. The azimuthally‐averaged
QuikSCAT's sea winds facilitates early identification of tropical depressions in 1999 hurricane season
Far from land and surface ship observations, most tropical depressions are identified by examining images from geostationary satellites for the presence of rotation of the convective cloud masses.
