Hadley cell

The major driving force of atmospheric circulation in the tropical regions is solar heating. Because of the Earth's 23.5 ° axial tilt, the sun is never more than a few tens of degrees from directly overhead at noon in the tropics; as a consequence, incident solar radiation provides maximum energy at the equator.

Scientists have discovered that wildfires release far more air-polluting gases than previously estimated. Many of these hidden emissions can transform into fine particles that are dangerous to breathe. The study shows wildfire pollution rivals ...
Earthquakes happen daily, sometimes with devastating consequences, yet predicting them remains out of reach. What scientists can do is map the hidden layers beneath the surface that control how strongly the ground shakes. A new approach speeds up ...
When a huge earthquake struck near Kamchatka, the SWOT satellite captured an unprecedented, high-resolution view of the resulting tsunami as it crossed the Pacific. The data revealed the waves were ...
A meltwater lake that formed in the mid-1990s on Greenland’s 79°N Glacier has been draining in sudden, dramatic bursts through cracks and vertical ice shafts. These events have accelerated in recent years, creating strange triangular fracture ...
CO2 can stimulate plant growth, but only when enough nitrogen is available—and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been overestimated by about 50 percent in major climate ...
Overfished coral reefs are producing far less food than they could. Researchers found that letting reef fish populations recover could boost sustainable fish yields by nearly 50%, creating millions of extra meals each year. Countries with high ...
Microplastics in rivers, lakes, and oceans aren’t just drifting debris—they’re constantly leaking invisible clouds of chemicals into the water. New research shows that sunlight drives this process, causing different plastics to release ...
Scientists have discovered a clever way to turn carrot processing leftovers into a nutritious and surprisingly appealing protein. By growing edible fungi on carrot side streams, researchers produced fungal mycelium that can replace traditional ...
Scientists have uncovered an extensive underwater vent system near Milos, Greece, hidden along active fault lines beneath the seafloor. These geological fractures act as pathways for hot, gas-rich fluids to escape, forming clusters of vents with ...
The Arctic is changing rapidly, and scientists have uncovered a powerful mix of natural and human-driven processes fueling that change. Cracks in sea ice release heat and pollutants that form clouds and speed up melting, while emissions from nearby ...
A new catalyst design could transform how acetaldehyde is made from renewable bioethanol. Researchers found that a carefully balanced mix of gold, manganese, and copper creates a powerful synergy that boosts efficiency while lowering operating ...
Scientists have built the most detailed 3D models yet of temperatures deep beneath Greenland. The results reveal uneven heat hidden below the ice, shaped by Greenland’s ancient path over a volcanic hotspot. This underground warmth affects how the ...
