Track Track and Moving Features

Typhoon Atsani (202020) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的W行转NW行Trend. formed初期 (10月29日至11月2日) , 系统自8°N, 148.5°E附近 toward NW direction稳定Moving, The latitude从8°N迅速N抬至19.1°N, During由148.5°EW进至128.1°E, 此阶段Moving速度较快, 横跨了广阔的洋面.

Go to November 3, there is a significant turn in the path. The system is almost stagnant near 20°N, 128.3°E and slightly E, then switched to the W path. During November 4 to 5, the Typhoon centerins the W line within the narrow latitude band of 20.4°N to 20.5°N, straight to the Strait of Bus and the Taiwan Island S area. After November 6, the path is again adjusted to the NW direction, and finally at November 7 at 20 weakened into Nameless, Position ranked at 22.6°N, 118.6°E. No landfall records during the entire life cycle, the main activity area is concentrated in the open ocean surface and near sea.

Intensity Evolution and Historical Comparison

Atsani’s Intensity change experienced the process of “slow enhancement – rapid eruption – rapid decline”. The initial period was Tropical Storm level (18m/s, 1000hPa) , Intensity remained stable in the first half of the path, the air pressure dropped only slightly to 995hPa. The critical enhancement period appeared on November 3 to 5, within 48h, the max wind jumped from 23m/s to 33m/s, the center lowest air pressure dropped to 975hPa, to the tiphoon peak. However, its peak stateined Time extremely short, the morning of November 6 began to weaken, the air pressure rose back to 982hPa, wind speed fell back to 28m/s. Go to Taiwan Strait and surrounding seas, after environmental factors, the system continued to weaken, until

Compared to the same name Typhoon, 2020 Athani's Intensity is weak at 2015 No. 16 Typhoon Atsani. 2015 is the same name Super Typhoon level, minimum pressure up to 910hPa, while 2020 Athani is only the ordinary Typhoon level, minimum pressure 975hPa, both of which have huge differences in peak intensity, reflecting the significant impact of the atmospheric flow background on the development of Typhoon in different years.
