Rainy season

At last, rainy season has come in this district.
Very humid days will continue for about a month... dull days...
though it is good to read book in house (^_^;

The warm pacific high pressure comes up from the south,
and the cold high pressure of the Sea of Japan (Ohohtsuku).
Between these high pressure a stationary front appears,
which is called "Baiu-zensen" (a plum front?), and this causes
the rainy season in Japan.
