Extreme lithium fractionation is observed when primary minerals in andesite are transformed to secondary clay minerals and then to oxides with intensive chemical weathering in a tropical climate.
During the late Quaternary period, a series of abrupt climate changes in the tropics and sub-tropics driven by changes in ocean circulation were both dramatic and disruptive.
The eastern tropical Pacific Ocean hasn’t warmed as much as climate change models projected. A new study shows that aerosols in the atmosphere could be responsible.
Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.
Spaceborne lidar shows that more ice than expected is leaving the tropical tropopause layer in the atmosphere.
Satellite observations show how tropical forest carbon fluxes respond to changes in water from climate variability.
Human-made channelization significantly accelerates peat decomposition and drives ground-surface deformation in tropical wetlands.
Despite increased photosynthetic activity at northern latitudes in recent decades, plant productivity in tropical zones suffers because of water limitations.
The diurnal variations of tropical cyclone intensification and decay are analyzed using satellite data for deep convective clouds.
Both satellite observations and model simulations reveal that more aggregated convection amplifies the increase in extreme rainfall events on a year-to-year basis.
