梅雨Tsuyu 梅雨入りTsuyu-Iri(Rainy Season, Onset of the Rainy Season)

In Japan, it rains a lot from the end of May to the beginning of July. Tsuyu is the name of the season in Japan when it rains a lot. Tsuyu-iri means that tsuyu is starting.

 

梅雨前線Baiu-Zensen (Seasonal Rain Front)

梅雨前線Baiu-Zensen uses the same kanji as 梅雨Tsuyu , but is read as "baiu zensen". During the tsuyu season, warm, moist air comes from the south of Japan, and cold, dry air from the north. The baiu-zensen is formed where these two air currents collide. This baiu-zensen being over Japan for a long time causes a rainy season with lots of rainfall.

 

降水確率Kosui Kakuritsu(Probability of Rain)

降水確率Kosui Kakuritsu means the probability of rainfall. When the weather forecast announces a 20% kosui kakuritsu in Tokyo, the probability of rainfall of 1 mm or more, is 20%. When it is 0%, there will be no rain in Tokyo.

 

ゲリラ豪雨Guerrilla Go-U (Unexpected Downpour)

ゲリラ豪雨Guerrilla Go-U is when a lot of rain falls suddenly in one place in a short period of time. It occurs mostly in summer. During a guerrilla go-u, trains may be delayed and river water may flood the streets, so please be careful.
