Blossoming of plum-trees
heralds the end of winter in Japan. As the Siberian
air masses that dominated the winter weaken, low
pressure and high pressure alternately pass through
Japan. Meanwhile, this part of the country also
would be enveloped by either one. When enveloped by
the high pressure the weather is generally good with
lots of sun and warmth but cold at night. On the
other hand, however, when low pressure passes there
is usually lots of rainfall caused by the moisture
brought in by the westerlies from the Sea of Japan.
This is the outline of the characteristic of the
springtime weather. |
