Scorpion wrote:Thats 80 knots?? Couldve fooled me for at least 130 kts! I wonder whats going on?
Scorpion, aside from the Joint Typhoon Warning Center, we also have the Japan Meteorological Agency, Hong Kong has another similar agency, Guam, and others. All at one point or the other each agency provide advisories over the same typhoon and always they say something different. In this case Japan says 80 knots and the JTWC says 110 knots. What is obvious seeing the visible images is that the overall structure of the system points toward a very strong tropical phenomenon of winds over 100 knots, thereafter, Japan shouldn't be an agency to rely on.

Let me clear things up on the difference in intensities between Tokyo (JMA) and Pearl Harbor (JTWC).
The JMA is the official warning agency for Ty Sonca, as well as any Western Pacific system. The JTWC is NOT an official warning agency. Their purpose is for the US Military.
The JMA, like a majority of the world, uses a ten-minute average on their wind speeds. The JTWC, like the US, uses a one-minute average.
To convert JMA's ten-minute average of 80kt, multiply by 1.14... 91kt.
Once again, as a reminder, the JMA's advisories are the official advisories for the WPAC whereas the JTWC is basically for morale use only. (They don't have to match the official WMO agencies)
As for the latest official word on Sonca... 110 mph (1-min avg) with a pressure of 940mb.

One more comment, to say that the JMA shouldn't be relied on is false. They are the official agency, designed by the WMO. If one simply converted the wind speeds from ten- to one-minute average, the end result is more logical.
Furthermore, the experience level is much higher at the JMA. The JTWC's experience level, on average, is a few years -- at best. Forecasters rotate in and out.
