Journal ArticleDOI
Annual water balance and seasonality of evapotranspiration in a Bornean tropical rainforest
Tomo'omi Kumagai,Taku M. Saitoh,Yoshinobu Sato,Hiroshi Takahashi,Odair J. Manfroi,Toshiyuki Morooka,Koichiro Kuraji,Masakazu Suzuki,Tetsuzo Yasunari,Hikaru Komatsu +9 more
TL;DR: In this paper, the results of 2 years combined field measurements of water vapor exchange with the atmosphere and simplified model calculations at Lambir Hills National Park, Sarawak, Malaysia (4812 0 N, 114802 0 E).
Journal ArticleDOI
Irregular droughts trigger mass flowering in aseasonal tropical forests in asia
Shoko Sakai,Rhett D. Harrison,Kuniyasu Momose,Koichiro Kuraji,Hidetoshi Nagamasu,Tetsuzo Yasunari,Lucy Chong,Tohru Nakashizuka +7 more
TL;DR: It is shown that this phenomenon is most likely triggered by irregular droughts based on 10 years of observations, and changes in the ENSO cycle resulting from global warming, may have serious ramifications for forest regeneration in this region.
Journal ArticleDOI
Transpiration, canopy conductance and the decoupling coefficient of a lowland mixed dipterocarp forest in Sarawak, Borneo: dry spell effects
Tomo'omi Kumagai,Tomo'omi Kumagai,Taku M. Saitoh,Yoshinobu Sato,Toshiyuki Morooka,Odair J. Manfroi,Koichiro Kuraji,Masakazu Suzuki +7 more
TL;DR: In this paper, the authors investigated key factors controlling materials-exchange, such as canopy (gc) and aerodynamic conductance (ga) and the decoupling coefficient (Ω), in an intact lowland mixed dipterocarp forest in Sarawak, Borneo.
Journal ArticleDOI
Ten-year evapotranspiration estimates in a Bornean tropical rainforest
Tomonori Kume,Nobuaki Tanaka,Koichiro Kuraji,Hikaru Komatsu,Natsuko Yoshifuji,Taku M. Saitoh,Masakazu Suzuki,Tomo'omi Kumagai +7 more
TL;DR: In this article, the authors conducted 10-year meteorological measurements and formulated a simplified big-leaf model that reproduces transpiration (Et), rainfall interception (Ei), and ET as the sum of these.
Journal ArticleDOI
Water cycling in a Bornean tropical rain forest under current and projected precipitation scenarios
Tomo'omi Kumagai,Tomo'omi Kumagai,Gabriel G. Katul,Taku M. Saitoh,Yoshinobu Sato,Odair J. Manfroi,Toshiyuki Morooka,Tomoaki Ichie,Koichiro Kuraji,Masakazu Suzuki,Amilcare Porporato,Amilcare Porporato +11 more
TL;DR: In this paper, a simplified hydrologic model is developed with its primary forcing term being rainfall statistics, and the effects of increased (or decreased) precipitation on increased or decreased) cloud cover and hence evapotranspiration is explicitly considered.
