Extra-Tropical Cyclones (ETCs) are responsible for billions of dollars worth of economic damage every year, and affect the entire mid-latitude regions of both hemispheres_ They are often termed windstorms by policymakers and industry, as the damage associated wi th their intense surface windspeeds is often widespread and catastrophic_ It is of paramount importance to tmderstand these hazardous phenomena_ In recent years vast amounts of observational ocean surface winds peed data have been made available, owing to the advent of the satellite era coupled with substantial improvements in remotely sensed ocean surface windspeed retrieval methods. These data have provided the opportunity to evaluate the current representation of ETC windspeeds in climate models. forecast analyses, and climate reanalyses. This had previously been difficult due to the obvious logistical constraints of obtaining reliable and continuous in-situ windspeed observations in ETC environments. This study utilises two satellite derived observational datasets in an attempt to provide verification of ETC surface windspeed structure of ECM\VF and NASA produced models, analyses and reanalyses. A particular emphasis is made to examine the ability of the datascts to simulate the most intense windspeeds within ETCs. These often occur on a small scale but cause the vast majority of damage associated with ETCs.
