Surface winds in a Himalayan valley are found to vary daily and seasonally due to factors including pressure gradient, advection, turbulent vertical mixing, and the presence of glaciers.

Finding Sources of Uncertainty in the Spatial Pattern of Warming
The planet is heating up, but uncertainty still exists about how temperatures will change in specific regions. A new study examines sources of uncertainty in the meridional pattern of warming.
How Ningaloo Niño Supercharges the El Niño–Southern Oscillation
The warm current cools the tropical Pacific and strengthens trade winds.
Exploring the Unknown of the Ross Sea in Sea Ice–Free Conditions
A team of polar scientists aboard the OGS Explora, cruising in rare ice-free conditions, discovered new evidence of ancient and modern-day ice sheet sensitivity to climatic fluctuations.
How Ice Rafting Events Affect Asian Monsoon Hydroclimate
Cave stalagmites provide isotopic evidence that Bond events and Heinrich events have more variable effects on Asian monsoon hydroclimate during the last glacial period than during the Holocene.
Sea Ice Loss Suppresses Some Effects of Climate Change
Polar amplification could counteract weather patterns shifting toward the poles.
Medieval Temperature Trends in Africa and Arabia
A synthesis of paleotemperature reconstructions from published case studies suggests warm onshore temperatures persisted across most of Afro-Arabia between 1000 and 1200 CE.
Pinpointing Effects of Hadley Cell Expansion
As a major atmospheric circulation system spreads farther poleward, some regions are drying out. But as time passes, will this drying be symmetrical across the globe?
Advancing Climate Forecasting
Better forecasts, new products: The World Climate Research Programme coordinates research aimed at improving and extending global climate forecasting capabilities.
Concepts for Dealing with the Complexity of Weather and Climate
A recent article in Reviews of Geophysics describes how a nonlinear approach and the concept of regimes helps our understanding.
