Western Pacific Tropical Cyclogenesis Precursors

The basic ingredients for tropical cyclogenesis have been well established: a sufficiently deep warm ocean layer, low-level cyclonic vorticity, weak vertical wind shear, and deep moist convection (e. et al. 2008) have attributed cyclogenesis to a variety of low-level precursor systems that enhance one or more of these ingredients. These studies have traditionally focused on features such as the...

Precursors of ENSO beyond the tropical Pacific

Phylogeny of Acridocarpus-Brachylophon (Malpighiaceae): implications for tertiary tropical floras and Afroasian biogeography.

A major tenet of African Tertiary biogeography posits that lowland rainforest dominated much of Africa in the late Cretaceous and was replaced by xeric vegetation as a response to continental uplift and consequent widespread aridification beginning in the late Paleogene. The aridification of Africa is thought to have been a major factor in the extinction of many African humid-tropical lineages,...

The Floras of Southern and Tropical Southeastern Yunnan Have Been Shaped by Divergent Geological Histories

The southern and tropical southeastern regions of the Yunnan Province in southwestern China have similar monsoonal climates and lowland tropical rain forest vegetations. The floras of both regions are dominated by tropical floristic elements (78.3% in southern Yunnan and 68.83% in southeastern Yunnan), and both belong to the Indo-Malaysian flora at the northern margin of tropical Asia. However,...

Salinity fronts in the tropical Pacific Ocean

This study delineates the salinity fronts (SF) across the tropical Pacific, and describes their variability and regional dynamical significance using Aquarius satellite observations. From the monthly maps of the SF, we find that the SF in the tropical Pacific are (1) usually observed around the boundaries of the fresh pool under the intertropical convergence zone (ITCZ), (2) stronger in boreal ...
