Pattern of rainfall distribution in the CentralPacific coast of Mexico
The CentralPacific coast of Mexico can be classified into four zones, each showing different rainfall patterns. As a result of tropical cyclone influence in the Pacific coast, the level of rainfall probability differs between zones. Such influence
A comparison of 500 hPa height patterns associated with anticyclones of Pacific and continental origin impacting the central Gulf Coast, United States

This research examines the 500 hPa circulation patterns that lead to the occurrence of days dominated by anticyclones of Pacific origin (Pacific Highs) over the central Gulf Coast. Although the geographically preferred zones of greatest height
variability are similar to those leading up to days dominated by anticyclones of continental origin (Continental Highs), variability centers on the northern fringes of the extratropics seem to support Pacific High activity to a greater extent than was found

Geomorphic features inherited from the mid-Holocene glacio-hydro-isostatic sea-level highstand that affected the centralPacific region influence the susceptibility of atoll islets to potentially enhanced wave erosion associated with rise in sea
level from global warming. Shoreline morphology on multiple islets of Funafuti atoll in central Tuvalu reflects a relative mid-Holocene sea-level highstand 2.2-2.4 m above modern sea-level. Exposed remnants of the lithified islet foundations serve
In this paper, the centralPacific cold event of 2008 and its exceptionally warm conditions in the eastern tropical Pacific are analyzed by using rainfall data of south Ecuadorian meteorological stations, sea surface temperatures in the El Niño3
and 1+2 regions, and simulations with the Weather Research and Forecasting (WRF) model. Since 2000, El Niño events unexpectedly provide below average rainfall while centralPacific La Niña conditions generate exceptional severe flooding in the normally
drier coastal plains. The novel sea surface temperature (SST) anomaly dipole structure between the eastern and central/western tropical Pacific and the weakening of El Niño events since 2000 could be due to natural decadal oscillations in the El Niño
background state, the Pacific Decadal Oscillation (PDO). However, the observed atmospheric patterns and the recent increase of the SST anomaly difference between the central and the eastern tropical Pacific resemble structures that also result from climate
Cultures of knowledge : investigating intellectual property rights and relations in the Pacific
The A. reveals the central role that global institutions now play in accelerating the universalisation of specific cultures for regulation : acting as powerful vectors for the transmission of particular types of knowledge and arbiters
of the normative bases of global regulatory regimes. Recent empirical evidence from the Pacific illustrates how the TRIPs regime facilitates the commodification and appropriation of intellectual, cultural and biological resources in that region and highlights
