dc.description.abstract | Data from the Global Precipitation Climatology
Project covering Central America, the Caribbean Sea, the
eastern tropical Pacific and northern South America are used
to compute four indexes that describe characteristics of the
Inter-Tropical Convergence Zone: the latitudinal center of
mass of precipitation, the longitudinal center of mass of
precipitation, the average precipitation in a region bounded by
10° S–25° N and 100° W–55° W, and the spread of the precipitation
patterns.Avery strong correlation is found between
summer latitudinal center of mass and a summer index of the
Caribbean Low-Level Jet suggesting connections between
Pacific and Caribbean climatic processes. The sign of the
correlation implies that when the jet is stronger (weaker) there
is a lower (higher) latitudinal center of mass and at the same
time less (more) precipitation in the Pacific slope of Central
America. The connection between the Caribbean and Pacific
climate is not only related to high-level wind convergence, but
it is proposed here that local convection and the establishment
of a zonal circulation may be playing a role in the process. The
circulation seems to be consistent during years when latitudinal
center of mass is lower than normal, apparently reinforcing
the jet, and presents weaker strength during years of
high latitudinal center of mass. The proposed mechanism is
explained in some detail. | es_ES |
