[Typhoon Bavi Suddenly Undergoes "Second Stage Evolution"? Chief Forecaster at the National Meteorological Center Explains Key Variables] Why is Typhoon Bavi fluctuating in strength? Wang Jing, chief forecaster at the National Meteorological Center, explained that Typhoon Bavi maintained its strength for a period after weakening to typhoon level. During this time, the convective structure in its center and surrounding area began to reorganize, gradually forming a double-eyewall structure. Given that there is still about a day before landfall, the overall intensity of the typhoon is expected to slightly increase as the outer and inner eyewalls contract successively. At the same time, the continuous influx of the southwest monsoon in the lower atmosphere provides a steady supply of energy to the typhoon; and the warm ocean surface also plays a positive role in maintaining and developing the typhoon. Therefore, the typhoon's intensity may further increase in the future. It is worth noting that during the period of maintaining the double-eyewall structure, the typhoon intensity often exhibits certain fluctuations. Specifically, the intensity will undergo a phased change: first increasing, then weakening due to the collapse of the inner eyewall, and finally strengthening again after the inner eyewall replacement process.
