The Role of Tropical Cyclones in Precipitation Over the Tropical and Subtropical North America
Tropical cyclones (TCs) are essential elements of the hydrological cycle in tropical and subtropical regions. In the present study, the contribution of TCs to seasonal precipitation around the tropical and subtropical North America is examined. When TC activity over the tropical eastern Pacific (TEP) or the Intra Americas Seas (IAS) is below (abovenormal), regional precipitation may be below (a...
متن کاملCryptolepiota, a new sequestrate genus in the Agaricaceae with evidence for adaptive radiation in western North America.
Phylogenetic analyses based on nLSU and ITS sequence data indicate that the sequestrate genus Gigasperma is polyphyletic. Gigasperma cryptica, which is known only from New Zealand, has affinities with the Cortinariaceae whereas G. americanum and two additional undescribed taxa from western North America are derived from Lepiota within the Agaricaceae. The three North American taxa appear to be ...
متن کاملA 400-year tree-ring chronology from the tropical treeline of North America.
High-elevation sites in the tropics may be particularly sensitive to rapid climate change. By sampling treeline populations, I have developed the first extensive (> 300 years) tree-ring chronology in tropical North America. The site is Nevado de Colima, at the western end of the Mexican Neovolcanic Belt, and the species studied is Mexican mountain pine (Pinus hartwegii). Despite past logging in...
متن کاملStationarity of the tropical pacific teleconnection to North America in CMIP5/PMIP3 model simulations
[1] The temporal stationarity of the teleconnection between the tropical Pacific Ocean and North America (NA) is analyzed in atmosphere-only, and coupled last-millennium, historical, and control runs from the Coupled Model Intercomparison Project Phase 5 data archive. The teleconnection, defined as the correlation between DecemberJanuary-February (DJF) tropical Pacific sea surface temperatures ...
متن کاملDaily Weather and Tree Growth at the Tropical Treeline of North America
We present here the 2001–2004 results of observational field studies aimed at quantifying tropical timberline climate and radial increment of Pinus hartwegii Lindl. trees on Nevado de Colima, in the middle of the North American Monsoon region. An automated weather station was installed at 3760 m a.s.l., 19834.7789N latitude, 103837.1809W longitude, within a forest where multi-century tree-ring ...
