IV. Seasonal Discussion

• The Siberian High has now become the dominant
  weather feature over the Western Pacific and the
  Far East. The leading edge of the cold polar air
  has pushed as far south as the Philippines. With
  the exception of the western Japanese coastal
  areas, conditions during November are quite
  similar to October.
• The northerly flow of dry air over Korea results
  in excellent weather there, but this same air, as
  it travels over the warm sea between Korea and
  Japan, picks up sufficient moisture to cause
  extensive clouds along the west coast of Japan.
  These clouds pile up against the mountains and
  cause overcast skies and precipitation.
• East of the mountain chain, clear skies are
  frequent, although smoke and haze mar the
  otherwise excellent weather. Poor weather is
  associated with frontal passages or developing
  low-pressure centers. Freezing temperatures and
  snow showers can be expected in Hokkaido, the
  northern part of Honshu, and Korea. Freezing
  temperatures and snow, although they do occur
  occasionally, are rare in the rest of Japan.
