From 1981 to 2010, the average annual precipitation measured at SeattleTacoma International Airport was 37.49 inches (952 mm). Annual precipitation has ranged from 23.78 in (604 mm) in 1952 to 55.14 in (1,401 mm) in 1950; for water year (October 1 September 30) precipitation, the range is 23.16 in (588 mm) in 197677 to 51.82 in (1,316 mm) in 199697. Due to local variations in microclimate, Seattle also receives significantly lower precipitation than some other locations west of the Cascades. Around 80 mi (129 km) to the west, the Hoh Rain Forest in Olympic National Park on the western flank of the Olympic Mountains receives an annual average precipitation of 142 in (3.61 m). Sixty miles to the south of Seattle, the state capital Olympia, which is out of the Olympic Mountains' rain shadow, receives an annual average precipitation of 50 in (1,270 mm). The city of Bremerton, about 15 mi (24 km) west of downtown Seattle, receives 56.4 in (1,430 mm) of precipitation annually.

There are also some extremely complex characters which have understandably become rather rare. According to Joel Bellassen (1989), the most complex Chinese character is / (U+2A6A5) zhe listen (helpinfo), meaning "verbose" and containing sixty-four strokes; this character fell from use around the 5th century. It might be argued, however, that while containing the most strokes, it is not necessarily the most complex character (in terms of difficulty), as it simply requires writing the same sixteen-stroke character long (lit. "dragon") four times in the space for one. Another 64-stroke character is / (U+2053B) zheng composed of xing/xing (lit. "flourish") four times.
What have become more rare?
complex characters

Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, many animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized.
