英文摘要	The paper investigates the retrieval of typhoon and hurricane surface barometric pressure by passive measurements. The SVR based retrieval algorithm is presented and the passive microwave measurements from the SNPP/ATMS are used for the algorithm training and verification. The assessment of the retrieval performance is done by comparing the case-by-case retrievals with dropsonde measurements and tropical cyclone best track data. The validation results show that the established retrieval algorithm can estimate typhoon and hurricane surface barometric pressure with the accuracy better than 8hpa. As a preliminary conclusion, this method can provide some important sea surface barometric pressure information for typhoon and hurricane structure and dynamic characteristics analysis and offers a new idea for the study of typhoon and hurricane from microwave radiometer data.
