The SummaryTyphoon Koguma (international code 202104) is a 2021 Northwest Pacific typhoon; peak intensity Tropical Storm, max wind 20m/s, minimum central pressure 990hPa, not in China Landfall, 2021-06-13 was numbered off, recording 27 track points.
Typhoon Koguma, international code 202104, international name Koguma, 2021 Northwest Pacific typhoon. Formed: 2021-06-11 14:00:00, ended: 2021-06-13 11:00:00. Peak intensity: Tropical Storm, minimum central pressure: 990 hPa, max wind: 20m/s.
Typhoon Koguma at 2021-06-11 14:00:00 at 17.6°N, 113.3°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 20 m/s (~72 km/h) and a minimum central pressure of 990hPa, recorded at 2021-06-12 23:00:00.
2021-06-13 11:00:00 After, Typhoon Koguma gradually weakened and was numbered off on 2021-06-13 11:00:00 was numbered off; its lifecycle recorded 27 track points.
Typhoon 'Koguma' (202104)'s life history is short, from formed to dispersed about 45h. According to the observation data, its overall Moving path shows a stable NW toward Trend, no apparent path turn or rotation phenomenon. in the initial phase (June 11, 14-12, 08h) , the system center is at Shain N's waters, coordinates from (17.6°N, 113.3°E) slow Moving to (18.4°N, 110.2°E), during which the latitude changes are small, mainly reflected by the longitudinal rapid shift W, showing guiding gas flow W with toward as the main segment.
Go to June 12 afternoon, the direction of the path was subtly adjusted, turning to WNW. From the 14th on June 12 (19.4°N, 108.6°E) to the 13th 07:00 (19.9°N, 106.1°E), the latitude increased by 0.5 latitudes in about 12h, while the length continued toward W. It is worth noting that in the near end of life (13.03°N, 108.6°E) , the latitude almost stagnated between 19.8°N-19.9°N, indicating that the system's Moving speed slowed or weakened by the terrain/environmental field caused the N toward score, and then continued toward W until dispersed at VietnamE's offshore region (105.1°E).
Koguma’s Intensity evolution underwent a typical process of “formed-enhanced-top-maintained-weakened”.Nameless, max wind 13m/s, Pressure 1000hPa. During the June 11 20 to 12 08 hours, the intensity remained stable, wind speedined at 15m/s, air pressure 998hPa.
The peak state appeared on June 12 23 to 13 07:00, up to 8h. During this period, the max wind reached 20m/s, the minimum pressure reached 990hPa. The data showed that during the peak period, although the Center continued to W move, but the wind speed and air pressure values remained highly stable, without further explosive enhancement, reflecting its internal structure although organized but energy input at balance. On June 13 11th, as the system moved out of the heated water zone or affected by land friction and dry air invasion, the intensity rapidly decreased, wind speed back to 16m/s, the air pressure rose back to 998hPa, reduced to Nameless and ended monitoring.
