A tropical plume sweeping into frozen America threatens an eruption of violent thunderstorms, tornadoes and ‘snow squalls’.

Air masses can change depending on their surroundings, and when combined, they can create active weather conditions, such as severe thunderstorms and strong cold fronts. Maritime Tropical (mT ...

This air mass originates in the Sahara Desert. In tropical latitudes this air mass is hot to very hot, with low relative humidity, bringing stable weather. As the ITCZ moves north it carries the ...

Near-inertial internal waves (NIWs) are crucial energy sources for deep-sea mixing, but the origins of deep NIWs have remained largely unknown. A research team led by Prof. Wang Fan from the ...

For example, the Polar Maritime Air Mass originates in the Poles and travels over the Arctic Sea, therefore it brings cold and wet weather. The Tropical Continental air mass originates in the ...
