Typhoon Halola, known in the Philippines as Typhoon Goring, was a long-lived and strong tropical cyclone in July 2015, which formed in the central Pacific Ocean and eventually struck Japan. Developing as the fifth named storm of the annual hurricane season south-southwest of Hawaii on July 11, Halola crossed the International Dateline late on July 12 and was recognized as the twelfth named storm of the annual typhoon season. It became a typhoon two days later. However, unfavorable conditions gradually decayed the system and weakened it into a tropical depression on July 18. Halola developed into a tropical storm again on July 20 and became a typhoon again on the next day. It formed an short-lived eye, and it received the name Goring from the PAGASA on July 23. Halola weakened into a severe tropical storm over the Ryukyu Islands on July 25 and made landfall over Kyushu on the next day, shortly before dissipating in the Tsushima Strait.
Meteorological history[edit]
Late on July 6, a tropical disturbance formed about 1,840 km (1,145 mi) southwest of Honolulu, Hawaii.[1] During July 10, the CPHC reported that atmospheric convection around the disturbance had persisted for long enough for the system to be considered a tropical cyclone.[2] As a result they initiated advisories on Tropical Depression One-C and estimated that the system had 1-minute sustained wind speeds of 30 mph (50 km/h).[2] Over the next day the system gradually intensified and organised further as it moved westwards, before it was named Halola by the CPHC during July 11, after it had intensified into a tropical storm.[3] The system continued to move westwards and slowly intensify over the next couple of days and moved out of the Central Pacific basin and into the Western Pacific as it crossed the International Dateline during July 12.[4][5] Within its first advisory on the system the Japan Meteorological Agency (JMA) reported that the system was a severe tropical storm.[6] With good dual outflow channels, both of the JMA and the Joint Typhoon Warning Center upgraded Halola to a typhoon on July 14, with a small but brief eye.[7][8] Although the JMA claimed that Halola strengthened a little later, the JTWC analyzed that it had struggled to intensify and begin to weaken.[9]
Because of high vertical wind shear, Halola became very disorganized near Wake Island on July 16 with convection sheared to the east side of its ragged low-level circulation center. As the result, the JMA downgraded the system to a tropical storm, so did the JTWC.[10][11] On July 18, with significant dry air from a TUTT cell to the north, Halola further weakened into a tropical depression, as only elongated and exposed low-level cloud lines wrapped into an ill-defined center.[12][13] Two days later, with improved poleward and equatorward outflow, Halola re-intensified into a tropical storm and continued tracking west-northwestward along a deep-layered subtropical ridge early on July 20, revealing a more symmetric and deeper moisture signature.[14][15] Moreover, it then took only six hours to intensify into a severe tropical storm, according to the JMA.[16]
Under warm sea surface temperature, low vertical wind shear and excellent diffluence aloft, Halola intensified into a typhoon again in the area between the Northern Mariana Islands and the Volcano Islands early on July 21, forming a significant but cloud-filled eye briefly;[17][18][19] besides, the JMA analyzed that the typhoon had reached peak intensity at noon, with ten-minute maximum sustained winds at 150 km/h (90 mph) and central pressure at 955 hPa (28.20 inHg).[20] Halola tried to form an eye again but filled quickly early on July 22, before the JTWC analysed that the typhoon had reached peak intensity at 18:00 UTC, with one-minute maximum sustained winds at 165 km/h (105 mph).[21][22] A well-defined eye appeared again but maintained briefly early on July 23, shortly before the PAGASA named the typhoon Goring.[23] After that, dry air began to wrap around the core, resulting a weakening convective structure.[24]
Failing to form a stable eye again, the typhoon started to weaken more on July 24, as dry air and northeasterly moderate vertical wind shear were together eroding the system.[25] Late on July 25, Halola passed near the Japanese islands of Amami Ōshima. On July 26, Halola made the first landfall over Saikai, Nagasaki at around 09:30 UTC and the second landfall over Sasebo, Nagasaki at 10:00 UTC.[26][27] Six hours after Halola's second landfall, Halola was declared dissipated.
Impact[edit]

Japan[edit]
Throughout the Daitō Islands, sugarcane farms were significantly affected by Typhoon Halola, resulting damage of about 154 million Japanese yen (1.2 million USD).[28]
In Akita Prefecture, the river levees were breached by the heavy rain due to the combination of a weather front with the typhoon.[29][30]
