The Hadley circulation is a key atmospheric circulation pattern in the tropics. It helps even out the temperature between the equator and the poles by moving energy and momentum toward higher ...

Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere. Scientists at the Research Unit ...

Birds and mammals are on extreme ends of the airflow spectrum. Mammals inhale oxygen-rich air and they exhale depleted air, exhibiting a so-called tidal flow pattern. In contrast, bird breath travels ...

Different types of airflow patterns in animal lungs. Mammals (top left) have a tidal airflow pattern where air moves to-and-fro through a branching network of bronchi. Birds (top right) have looping ...

Analysis of airflow patterns around models of mushrooms and fresh fruiting bodies in a low speed wind tunnel showed division of the airstream at the leading edge of the cap, an increase in wind speed ...

Take a deep breath in. Slowly let it out. You have just participated in one of the most profound evolutionary revolutions on Earth--breathing air on land. It's unclear how the first vertebrates ...
