Typhoon Lan

[knocker]

Computer model projections show that Typhoon Lan may grow to be a particularly large storm in the Northwest Pacific as it intensifies and moves toward Japan. Eventually, it will recurve out into the North Pacific, where some of its energy will interact with the jet stream (the river of fast-flowing air at high altitudes that helps steer weather systems), perturbing what has been a rather straight west-to-east airflow into a series of upper level waves or undulations. These dips, or "troughs" in the jet, as well as bulges or "ridges," will trigger changes in the weather across North America and beyond.

Looks like the typhoon was rapidly weakening as it made landfall (reportedly as cat-2) southwest of Tokyo, the eye went right over the city at about 21z Oct 22 (Monday morning 23rd local time) based on regional wind patterns, but peak gusts at three Tokyo airports were about 60 knots, pressure appeared to be 965 mbs at that point. Temperature briefly spiked at 25 C at Narita northeast of the city centre. The remnants are now east of Hokkaido.

Typhoon Lan will combine w/extratropical system east of Kamchatka peninsula & re-deepen to 940 mb (potent for late October) H/t RM
