Atmospheric instability is a condition where the Earth's atmosphere is considered to be unstable and as a result local weather is highly variable through distance and time. [ clarification needed ] [ 1 ] Atmospheric instability encourages vertical motion, which is directly correlated to different types of weather systems and their severity.
Some atmospheric conditions, such as very warm, moist, air in an atmosphere that cools rapidly with height, can promote strong and sustained upward air movement, possibly stimulating the formation of cumulus clouds or cumulonimbus (thunderstorm clouds). In that situation the potential energy of the atmosphere to cause upward air movement is ...
Spain is predicted to be highly vulnerable because of uneven availability of water resources, and due to existing demands. As a result of its geographic and socio-economic characteristics, Spain is regarded as one of the most vulnerable countries to climate change in the European Union.
In fact, Spain is sometimes described as the most climatically diverse country in Europe [1] and has 13 different Köppen, climates. [ 2 ] [ 3 ] [ 4 ] The four most dominant climates in the country include: The hot-summer Mediterranean climate ( Csa ), the warm-summer Mediterranean climate ( Csb ), the semi-arid climate ( BSk ) and the oceanic ...
Atmospheric convection is the result of a parcel-environment instability (temperature difference layer) in the atmosphere. [ jargon ] Different lapse rates within dry and moist air masses lead to instability.
Several bodies have been found after parts of southern and eastern Spain were hit by severe flash flooding on Tuesday, with some locations receiving up to 12 inches of rain in just a few hours ...
Thunderstorms occur when denser, drier cold air is pushed over warmer, humid air, conditions scientists call atmospheric instability. As that happens, an updraft is created when the warm air rises.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
