Blossoming of plum-trees, seen
everywhere, heralds the end of winter in Japan. As
spring sets in, low and high atmospheric
pressure systems move by turns from west to east.
enveloped with the high pressure one,
weather is generally good with lots of sun
and warmth in daytime, but cold at night. On the
other hand, however, when visited by the low
pressure mass, we have relatively lots of
rainfall due to the moisture brought in from the
Sea of Japan by the westerlies. This is the
characteristic of springtime weather in and around
faced on the Sea of Japan.
