Typhoon Matmo

The origins of Matmo can be tracked back to an area of low pressure that developed in the Intertropical Convergence Zone (ITCZ), about 150 nautical miles (280 km; 170 mi) east of Chuuk on July 9, 2014.[1] Over the next 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.[2] Located in a 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.[3] Around the same time, the Regional Specialized Meteorological Center (RSMC) in Tokyo, operated by the Japan Meteorological Agency (JMA) started tracking the system as a tropical depression.[4] Tracking northwestward at around 2 knots (3.7 km/h; 2.3 mph), the depression continued to consolidate while the JTWC initiated advisories on it with the identifier '10W'.[5] In the evening of July 17, the JMA upgraded 10W to a Tropical Storm, and named it Matmo.[6] The subsequent 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.[7][8] Over the next 24 hours, Matmo sped up on its track, as it drifted north-westwards at over 9 knots (17 km/h; 10 mph), passing some 244 nautical miles (452 km; 281 mi) north-northwest of Koror, Palau.[9] Around that time, the JMA upgraded Matmo to a Severe Tropical Storm.[10]

By 19 July, the LLCC 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.[11] On that day, the JMA reported 64 knots (119 km/h; 74 mph) winds at the center of the storm, thereby upgrading it to a Typhoon.[12] The convective banding around the LLCC started to curl inwards as an eye-like feature started developing.[13] However, the LLCC became obscured again by the next day.[14] Matmo was kept from intensifying further by the vertical wind shear produced by the subtropical ridge steering the typhoon. The wind shear finally started to relax on July 21 as Matmo approached the axis of the ridge.[15] Tracking some 500 nautical miles (930 km; 580 mi) south-southwest of Okinawa, the typhoon's LLCC expanded in size and consolidated further.[16] By the next day, Matmo became more organized as a second convective rainband developed along the northern half of the system. The poleward outflow also improved and fueled the expansion of convection around the LLCC.[17] The storm reached peak intensity on July 22. The JMA was reporting a 10-minute average windspeed of 75 knots (139 km/h; 86 mph) while the JTWC was reporting a 1-minute average windspeed of 85 knots (157 km/h; 98 mph) around the center, making it a Category 2 Typhoon on the Saffir–Simpson scale.[18][19] A broad eye feature developed with strong convective rainbands wrapped tightly into it. Located roughly 158 nautical miles (293 km; 182 mi) south of Taipei, Taiwan, Matmo was bringing torrential rainfall and squally winds to all regions of the nation.[20] Maximum significant wave height was reportedly 30 feet (9.1 m).[21] The storm continued on it's northwesterly track at 13 knots (24 km/h; 15 mph) and made landfall in Taiwan, south of Hualian at peak intensity. The strongest gusts of 212 km/h (132 mph) were recorded on Orchid Island.[22]

Matmo emerged into the Taiwan Strait early on July 23. Most of its rainbands had thinned down and the LLCC became very organised as low level inflow was disrupted by Taiwan's rugged terrain. [23] The JMA downgraded Matmo into a severe tropical storm and eventually a tropical storm during this process.[24][25] Matmo weakened continuously due to land interaction. The typhoon made its second landfall on China while parts of it's rainbands were still over Taiwan and the Philippines. Following its landfall south of Putian, the JTWC downgraded Matmo into a tropical storm, issuing their final advisory on the system.[26] The JMA, however, continued tracking Matmo as a tropical storm until it became extratropical on July 25.[27]
