Japanese people are a nation and an ethnic group that is native to Japan and makes up 98.5% of the total population of the country. Worldwide, approximately 129 million people are of Japanese descent; of these, approximately 125 million are residents of Japan. People of Japanese ancestry who live outside Japan are referred to as nikkeijin(日系人), the Japanese diaspora. The term ethnic Japanese is often used to refer to Japanese people, as well as to more specific ethnic groups in some contexts, such as Yamato people and Ryukyuan people. Japanese are one of the largest ethnic groups in the world.
The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices orbit each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one. Extratropical cyclones typically engage in binary interaction when within 2,000 kilometres (1,200 mi) of one another, while tropical cyclones typically interact within 1,400 kilometres (870 mi) of each other.
