ENSO

El Niño-Southern Oscillation (ENSO) is a global coupled ocean-atmosphere phenomenon. The Pacific ocean signatures, El Niño and La Niña are important temperature fluctuations in surface waters of the tropical Eastern Pacific Ocean. The name El Niño, from the Spanish for "the little boy", refers to the Christ child, because the phenomenon is usually noticed around Christmas time in the Pacific Ocean off the west coast of South America. La Niña, similarly, means "the little girl". Their effect on climate in the southern hemisphere is profound. These effects were first described in 1923 by Sir Gilbert Thomas Walker from whom the Walker circulation, an important aspect of the Pacific ENSO phenomenon, takes its name. The atmospheric signature, the Southern Oscillation (SO) reflects the monthly or seasonal fluctuations in the air pressure difference between Tahiti and Darwin. The most recent occurrence of El Niño started in September 2006 and lasted until early 2007.. From June 2007 on, data indicated a weak La Niña event.

Ensō is perhaps the most common subject of Japanese calligraphy, symbolizing enlightenment, strength, elegance, the universe, and the void; it is also an "expression of the moment". It is believed by many that the character of the artist is fully exposed in how he paints ensō, and that only one who is mentally and spiritually whole can paint a true ensō. Some artists will paint ensō daily, as a kind of spiritual diary.
