Typhoon Mirinae (2009)
Encyclopedia
Typhoon Mirinae was the 34th depression and the 14th typhoon in the 2009 Pacific typhoon season
.
(JTWC) reported that an area of convection was developing over a elongated and broad low level circulation center within a monsoon trough about 500 km, 315 miles to the southeast of Pohnpei
. The low level circulation center was located under a region of favourable divergence, however it was located in area of moderate to high vertical windshear which was hampering the low level circulation centers attempts to organize. Over the next couple of days the vertical windshear relaxed and as a result convection started to develop further with a Tropical Cyclone Formation Alert
being issued by the JTWC late on October 25 after the Japan Meteorological Agency
(JMA) had designated the disturbance as a weak tropical depression. The JTWC then designated the depression as 23W early the next morning as there had been an increase in convection consolidating near a developing low level circulation center. The JTWC then reported later that day that the depression had intensified into a Tropical Storm, however the JMA did not follow suit until early the next day when they assigned the international name of Mirinae to the storm as it passed over the island of Rota
in the Northern Mariana Islands
