2.7 Meteorological Information
2.7.1 Synoptic Weather
According to the surface weather chart at 09:00 on January 21, there was a depression
with a central atmospheric pressure of 1,006hPa over the Sea of Japan S.W. of Hakodate,
and a high-pressure system of 1,032hPa N.E. of Hakodate, both proceeding N.E. at a speed
of 15–25 knots. At 15:00, the depression had deepened to 1,000hPa and the high-pressure
system had increased to 1,036hPa. At the time of the accident the distance between the
isobars were narrowing and the atmospheric pressure gradient was very high. According to
this situation, at a time of accident, atmospheric pressure situation was estimated to blow
strong winds, winter style distribution of atmospheric pressure changed, as the low pressure
12
system approaching, supreme N-E wind was weaken.
A warning of strong airport surface winds was issued at 11:40 on the same day, and
airport weather information related to heavy rain was issued at 11:45. At the time of the
accident the wind velocity measurement device situated near runway 12 measured the wind
as 130–140° at an average speed of 28kt, with a maximum speed of 40kt and a minimum
speed of around 20kt.
Further, according to automatic recordings of real-time wind direction and speed at the
Hakodate Airport branch of the Meteorological Agency’s Hakodate Oceanic Meteorological
Office, there was no difference in wind direction or speed between the 12 and 30 ends of the
runway. (See Figs. 3 ~ 7).
