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. |
