E-mail: [email protected] Fax: 808-471-4581 Co-Chairs: Chris Velden, John LeMarshall 0.1e.1 Introduction The Joint Typhoon Warning Center (JTWC), Pearl Harbor Hawaii, is responsible for providing tropical cyclone forecasts to the United States Department of Defense, and Department of State for the Pacific and Indian Oceans.
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. …

T3 raised early Wednesday afternoon, and T8 just minutes ago (Wednesday night 22:40 local). Most flights still going out as scheduled (looks like just some cargo flights cancelled), CX projects some delays in landing for Thursday morning. The arrivals board looks like some of the other airlines (UA, NW, KE, OZ, NH) have delayed some flts into …
EV2 - Joint Typhoon Warning Center Cyclone Data. The Joint Typhoon Warning Center (JTWC) is responsible for typhoon forecasts and warnings for the Western Pacific and Indian Ocean basins. After each storm, the JTWC stores its records in accordion-style folders, or "wallets". Facing prohibitive storage costs and space constraints for historical ...
Using the tropical cyclone best track data from the U.S. Department of Defense's Joint Typhoon Warning Center (JTWC), Webster et al. found that between the two consecutive 15-year periods of 1975-1989 and 1990-2004, the percentage of typhoons in the western North Pacific meeting the definition of categories 4 and 5 on the Saffir-Simpson …
Abstract The current version of the Statistical Typhoon Intensity Prediction Scheme (STIPS) used operationally at the Joint Typhoon Warning Center (JTWC) to provide 12-hourly tropical cyclone intensity guidance through day 5 is documented. STIPS is a multiple linear regression model. It was developed using a "perfect prog" assumption and …
[1] This paper presents the results of an investigation on the interannual variations of tropical cyclone (TC) size, defined as the average radius of 15 m s −1 surface winds, over the western North Pacific from 1999 to 2002. The wind data are from QuikSCAT. The average TC size is found to increase from 1999 to 2002, with the TC …
The responses to tropical cyclones of ocean wave characteristics in deep water of the western Atlantic Ocean have been investigated extensively, but not the regional seas in the western Pacific such as the South China Sea (SCS), due to a lack of observational and modeling studies there. Since monsoon winds prevail in the SCS but not in the western …
Typhoons are what make the waves on the east coast of the Philippines - moving through the Western Pacific Ocean and the Philippines Sea, bringing powerful groundswells the the east coast between April and November, alone with favourable offshore southwest "habagat" winds. The season usually starts slowly, and there can be …
Abstract Axisymmetric temperatures and gradient-balanced winds associated with tropical cyclones derived from the Advanced Microwave Sounding Unit are stratified by the 24-h averaged vector difference of the horizontal wind between 200 and 850 hPa (or vertical wind shear). Using 186 total cases that are limited to tropical cyclones with …
JTWC, RSMC-Tokyo, and HKO all classified Nida as a typhoon. On the basis of maximum one-minute winds of 140 knots given by JTWC best track intensity, Nida would be a Category 5 typhoon. However, RSMC-Tokyo best track data give Nida's maximum 10-minute winds as 95 knots.
The climatology of near-equatorial typhoons over the western-north Pacific are fully investigated using the JTWC (Joint Typhoon Warning Center) typhoon record from 1951 to 2006. The result shows that there are seasonal and decadal variations, as well as a distinctive spatial distribution, of such events. Among them, Typhoon Vamei is an …
JTWC (Joint Typhoon Warning Centre) for the years 1979-2004, but have included a comparison with the LR-RSMC (La Reunion – Regional Specialised Meteorological Centre) record, as shown in Figure 1. Kuleshov and de Hoedt (2003) have found an increased cyclone frequency between 85-105°E during La Niña years compared to El Niño. Bessafi
