Locations of tropical climates, with subtypes.

  Af—Tropical rainforest climate.

  Am—Tropical monsoon climate.

  Aw—Tropical savanna climate.

Beach in Naples, Florida lined with coconut trees is an example of a tropical climate. Although it lies in the subtropics over a hundred miles north of the tropic of cancer, the warm waters of the Gulf of Mexico give it a monthly mean temperature never under 18 °C (64 °F), classifying its climate as tropical.

Intertropical Convergence Zone vertical velocity at 500 hPa, July average in units of pascals per second. Ascent (negative values) is concentrated close to the solar equator; descent (positive values) is more diffuse.

A tropical climate is a climate of the tropics. In the Köppen climate classification it is a non-arid climate in which all twelve months have mean temperatures above 18 °C (64 °F). Unlike the extra-tropics, where there are strong variations in day length and temperature, with season, tropical temperature remains relatively constant throughout the year and seasonal variations are dominated by precipitation.

Subtypes[link]

Within the tropical climate zone there are distinct varieties based on precipitation:

• Tropical rainforest climate (Af):^[1] All twelve months have average precipitation of at least 60 mm (2.4 in). These climates usually occur within 5–10° latitude of the equator. In some eastern-coast areas, they may extend to as much as 25° away from the equator. This climate is dominated by the Doldrums Low Pressure System all year round, and therefore has no natural seasons.
• Tropical monsoon climate (Am):^[1] This type of climate, most common in South and Central America, results from the monsoon winds which change direction according to the seasons. This climate has a driest month (which nearly always occurs at or soon after the "winter" solstice for that side of the equator) with rainfall less than 60 mm, but more than (100 − [total annual precipitation {mm}/25]).
• Tropical wet and dry or savanna climate (Aw):^[1] These climates generally have a pronounced dry season, with the driest month having precipitation less than 60 mm and also less than (100 − [total annual precipitation {mm}/25]).
  • Examples:
    • Mumbai, Maharashtra, India
    • Jakarta, Indonesia
    • Rio de Janeiro, Rio de Janeiro, Brazil
    • Veracruz, Veracruz, Mexico
    • Port-au-Prince, Haiti
    • Dar es Salaam, Tanzania
    • Lagos, Lagos State, Nigeria
    • Darwin, Northern Territory, Australia
    • Naples, Florida, United States
    • Honolulu, Hawaii, United States^[2]

Note that, in this scheme, many places within the tropics do not have a tropical climate: for example, the Sahara desert. Mountaintops within the tropics, e.g. Mount Kenya, can be cold.

Intertropical Convergence Zone[link]

Because of the effect of sun angle on climate most areas within the tropics are hot year-round, with diurnal variations in temperature exceeding seasonal variations. Seasonal variations in tropical climate are dominated by changes in precipitation, which are in turn largely influenced by the tropical rain belt or Intertropical Convergence Zone (ITCZ), a portion of the Hadley cell. The ITCZ is shown, for July average, in the graphic. Areas of ascending air have heavy rainfall; areas of descending air are dry. The ITCZ somewhat follows the solar equator throughout the year, but with geographical variations, and in some areas (India) is heavily influenced by local large-scale monsoons.

Demetri Martin (born May 25, 1973) is an American comedian, actor, artist, musician, writer and humorist. Martin is best known for his work as a stand-up comedian, contributor on The Daily Show and for his Comedy Central show Important Things with Demetri Martin.

Early life[link]

Demetri Martin was born to a Greek American family^[1] in New York City, New York, and grew up in Toms River, New Jersey. He is the son of Lillian, a nutritionist, and Dean C. Martin, now deceased, a Greek Orthodox priest.^[2] Martin graduated from Yale University in 1995. Although he was accepted into Harvard Law School, he went to New York University School of Law after he received a full scholarship.^[3]

Career[link]

In 2001, Martin caught his first big break in stand-up comedy when he appeared on Comedy Central's stand-up showcase Premium Blend. At the 2003 Edinburgh Festival Fringe he won the Perrier award with his show If I....^[4] The show was turned into a British television special in 2004. From 2003 to 2004, Martin wrote for Late Night with Conan O'Brien.^[5] In 2004, Martin had his own Comedy Central Presents stand-up special. His special was divided into three parts. In the first, he performed in traditional stand-up comedy fashion. In the second segment, he used humorous drawings as visual aids, which would serve either as the punchline or a background. During the third segment, he played a guitar and put on a pseudo-play where he would strum his guitar while alternating between playing harmonica and talking; some of his comedian friends dressed as fairies and dragons acted according to the story he was telling, detailing the magical land where his jokes came from. Martin's mother and grandmother also appeared.

Since late 2005, he has been credited as a contributor on The Daily Show, on which he has appeared as the named "Senior Youth Correspondent" and on which he hosts a segment called "Trendspotting". He has used this segment to talk about so-called hip trends among youth such as hookahs, wine, guerilla marketing and Xbox 360. A piece about social networking featured his profile on MySpace.^[6] On March 22, 2007, Demetri made another appearance on The Daily Show, talking about the Viacom lawsuit against Google and YouTube.

He has recorded a comedy CD/DVD titled These Are Jokes, which was released on September 26, 2006. This album also features Saturday Night Live member Will Forte and stand-up comedian Leo Allen.

Martin returned to The Daily Show on March 22, 2006, as the new Youth Correspondent, calling his segment "Professional Important News with Demetri Martin". In 2007, he starred in a Fountains of Wayne music video for "Someone to Love" as Seth Shapiro, a character in the song. He also starred in the video for the Travis single "Selfish Jean", in which he wears multiple t-shirts with lyrics written on them.

On September 2, 2007, Martin appeared on the season finale of the HBO series Flight of the Conchords. He appeared as a keytar player named Demetri.^[7]

He also had a part in the movie The Rocker (2008) starring Rainn Wilson. Martin played the part of the videographer when the band in the movie was making their first music video.

In 2009, he hosted and starred in his own television show called Important Things With Demetri Martin on Comedy Central. Later in June, it was announced his show had been renewed for a second season.^[8] The second season premiered, again on Comedy Central, on February 4, 2010. Martin has stated that Important Things will not return for a third season.

Prior to completing work on his second season, Martin starred in the comedy-drama film Taking Woodstock (2009), directed by Ang Lee, which premiered at the 2009 Cannes Film Festival. In the film Martin plays Elliot Tiber, a closeted gay artist who has given up his ambitions in the city to move upstate and help his old-world Jewish family run their Catskill Mountains motel. The film is based on the book written by Tiber.

On April 25, 2011, Martin released his first book, titled This Is a Book by Demetri Martin.

Martin was slated to portray Paul DePodesta as Oakland Athletics assistant GM to Billy Beane in the 2011 movie Moneyball, however was dropped and Jonah Hill took his place in the movie.

Plans[link]

Martin sold his movie concept Will to DreamWorks; he is expected to play a key supporting role.^[9] He will play the lead in the film Moon People, a pitch that he sold to Columbia Pictures.

Martin also signed a blind script deal with CBS in October 2010 to produce, write, and star in his own television series.^[10]

After CBS was shown the pilot for the series, they decided not to air it.^[11]

On August 11, 2011, Fox ordered a presentation of a new animated show they might air.^{[citation needed]}

[edit] If I

If I is a Perrier Comedy Award-winning comedy one-man show written and performed by Demetri Martin at the 2003 Edinburgh Festival Fringe.^[12] It was also aired on British television as a special. The show is an autobiographical examination of Martin's life, as seen through various definitions of the word "if."

The title of the special comes from a lengthy palindromic poem that Martin wrote; the words "if I" are at the center of the poem.^[13]

Comedic style[link]

Martin is known for being an unconventional stand-up comic. He uses one-liners and drawings on a "large pad", as well as accompanying his jokes with music on either guitar, harmonica, piano, keyboard, glockenspiel, toy bells, ukulele, or tambourine, sometimes all at once.^[14] He has cited comedian Steven Wright as an important influence (both use deadpan one-liners in their acts) and he is also a fan of Bill Cosby.^[15]

Personal life[link]

According to a July 2011 interview on the WTF with Marc Maron podcast, Demetri had a short-lived marriage to a girl he knew from high school. They began dating after high school and got married when he was in NYU Law School and she was attending NYU Medical School. He was aged 25 and in the end of his marriage when his stand-up career began.^[3]

He is extremely allergic to nuts and peanuts.^[16]

Martin moved to Santa Monica, California in 2009.^[17]
