Typhoon Matmo (2014)

{{storm path|Matmo 2014 track.png}}

The origins of Matmo can be tracked back to an area of low pressure that developed in the Intertropical Convergence Zone, about {{convert|280|km|mi|abbr=on}} east of Chuuk on July 9, 2014.{{cite web|title=ABPW10 on 2014-07-09 |url=http://gwydir.demon.co.uk/advisories/ABPW10-PGTW_201407090600.htm |publisher=US Naval Observatory |accessdate=15 November 2014 |url-status=unfit

few days, the system's low-level circulation center (LLCC) slowly consolidated with convective banding developing around its southern periphery and a burst of convection over its center.{{cite web|title=ABPW10 on 2014-07-16 |url=http://gwydir.demon.co.uk/advisories/ABPW10-PGTW_201407160600.htm |publisher=US Naval Observatory |accessdate=15 November 2014 |url-status=unfit

favorable region, the system slowly intensified, prompting the Joint Typhoon Warning Center (JTWC) to issue a Tropical Cyclone Formation Alert (TCFA) on the system, on July 16.{{cite web |title=TCFA for Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WTPN21-PGTW_201407161130.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=dead

time, the Regional Specialized Meteorological Center in Tokyo, operated by the Japan Meteorological Agency (JMA) started tracking the system as a tropical depression.{{cite web

six hours saw the JTWC recognizing Matmo as a tropical storm and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) naming it Henry as it entered the Philippine area of responsibility.{{cite web |title=Matmo enters PAR |url=http://www.pagasa.dost.gov.ph/tropical-cyclone/weather-bulletin-update/141-tropical-cyclone/henry-2014-bulletin/1096-1 |publisher=PAGASA

time, the JMA upgraded Matmo to a severe tropical storm.{{cite web|title=STS Matmo – JMA |url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407190000.htm |publisher=RSMC Tokyo |accessdate=15

|archivedate=May 23, 2024 }}

By July 19, the center of Matmo had become obscured as deep central convection developed over it. Microwave satellite imagery showed improving convective banding despite the overall structure of the storm being slightly elongated.{{cite web|title=Prognostic Reasoning for Warning 08 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407190900.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523091812/https://www.webcitation.org/6RCclR37O?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407190900.htm |archivedate=May 23, 2024 }} Subsequent intensification resulted in the JMA upgrading Matmo to a typhoon.{{cite web|title=TY Matmo from RSMC Tokyo |url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407190600.htm |publisher=RSMC Tokyo |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523091652/https://www.webcitation.org/6RCcC5igg?url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407190600.htm |archivedate=May 23, 2024 }} The convective banding around the LLCC started to curl inwards as an eye-like feature started developing.{{cite web|title=Prognostic Reasoning for Warning 10 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407192000.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523091731/https://www.webcitation.org/6RCcl2wAZ?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407192000.htm |archivedate=May 23, 2024 }} Increasing wind shear stemming from the subtropical ridge steering the typhoon inhibited further organization. By July 21, the shear abated somewhat and allowed for some intensification.{{cite web|title=Prognostic Reasoning for Warning 15 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407210300.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523091852/https://www.webcitation.org/6RE6BZgGf?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407210300.htm |archivedate=May 23, 2024 }} Tracking well to the southwest of Okinawa, the typhoon increased in both size and organization,{{cite web|title=Prognostic Reasoning for Warning 17 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407211500.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092025/https://www.webcitation.org/6RFbiXVzD?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407211500.htm |archivedate=May 23, 2024 }} with a secondary convective rainband developing along the northern half of the system by July 22. Upper-level outflow also improved and fueled the expansion of convection.{{cite web|title=Prognostic Reasoning for Warning 19 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407220300.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523091933/https://www.webcitation.org/6RFbiAlqE?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407220300.htm |archivedate=May 23, 2024 }} A broad eye feature developed with strong convective rainbands wrapped tightly into it.{{cite web|title=Prognostic Reasoning for Warning 21 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407221500.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092422/https://www.webcitation.org/6RHDAkFQ0?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407221500.htm |archivedate=May 23, 2024 }} The storm reached peak intensity on July 22, with maximum sustained winds of {{convert|140|km/h|mph|abbr=on}} and a central barometric pressure of 960 mbar (hPa; {{convert|960|mbar|inHg|lk=on|abbr=on|sigfig=4|disp=out}}).{{cite web|title=Peak Intensity from JMA |url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407220000.htm |publisher=JMA |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092053/https://www.webcitation.org/6RFbZeuh9?url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407220000.htm |archivedate=May 23, 2024 }} Around the same time the JTWC estimated Matmo to have acquired one-minute sustained winds of {{convert|155|km/h|mph|abbr=on}}, ranking the system as a Category 2-equivalent on the Saffir–Simpson hurricane wind scale.{{cite web|title=Peak Intensity from JTWC |url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201407220900.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092254/https://www.webcitation.org/6RHD7UGOD?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201407220900.htm |archivedate=May 23, 2024 }} The storm continued on its northwesterly track and made landfall in Taiwan, south of Hualien. The strongest gusts of {{convert|212|km/h|mph|abbr=on}} were recorded on Orchid Island.{{cite web|title=Typhoon Matmo made landfall in Taiwan, tracking toward southeastern China|date=22 July 2014 |url=http://thewatchers.adorraeli.com/2014/07/22/typhoon-matmo-made-landfall-in-taiwan-tracking-toward-southeastern-china/|publisher=The Watchers|accessdate=15 November 2014}}

Emerging over the Taiwan Strait early on July 23, Matmo was greatly weakened by its passage over Taiwan. Convective rainbands diminished significantly and its circulation became severely disrupted by Taiwan's rugged terrain.{{cite web|title=Prognostic Reasoning for Warning 23 on Typhoon Matmo |url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407230300.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092334/https://www.webcitation.org/6RHDAJGnW?url=http://gwydir.demon.co.uk/advisories/WDPN31-PGTW_201407230300.htm |archivedate=May 23, 2024 }} The JMA downgraded Matmo into a severe tropical storm and eventually a tropical storm during this process.{{cite web|title=JMA Downgrades Matmo to STS |url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407221800.htm |publisher=JMA |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092214/https://www.webcitation.org/6RHCxrTrU?url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407221800.htm |archivedate=May 23, 2024 }}{{cite web|title=JMA Downgrades Matmo to a Tropical Storm |url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407230600.htm |publisher=JMA |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092133/https://www.webcitation.org/6RHCx62tA?url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407230600.htm |archivedate=May 23, 2024 }} The JTWC, however, maintained Matmo as a typhoon during this time. The storm made its second landfall on China, south of Putian, while parts of its rainbands were still over Taiwan and the Philippines. Once onshore, the JTWC downgraded Matmo to a tropical storm and issued their final advisory.{{cite web|title=JTWC Final Warning on Matmo |url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201407231500.htm |publisher=JTWC |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092455/https://www.webcitation.org/6RIkEBLjO?url=http://gwydir.demon.co.uk/advisories/WTPN31-PGTW_201407231500.htm |archivedate=May 23, 2024 }} The JMA, however, continued tracking Matmo as a tropical storm until it became extratropical on July 25.{{cite web|title=Matmo becomes extra-tropical |url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407250600.htm |publisher=JMA |accessdate=15 November 2014 |url-status=unfit |archiveurl=https://archive.today/20240523092539/https://www.webcitation.org/6RKEGZOMz?url=http://gwydir.demon.co.uk/advisories/WTPQ20-RJTD_201407250600.htm |archivedate=May 23, 2024 }}
