A baroclinic instability is a fluid dynamical instability of fundamental importance in the atmosphere and ocean. It can lead to the formation of transient mesoscale eddies, with a horizontal scale of 10-100 km. [1] [2] In contrast, flows on the largest scale in the ocean are described as ocean currents, the largest scale eddies are mostly created by shearing of two ocean currents and static ...
Erdkunde publishes scientific articles covering the whole range of physical geography and human geography. The journal offers state of the art reports on recent trends and developments in specific fields of geography and comprehensive and critical reviews of new geographical publications. High-quality maps and large-format supplements are of ...
Geographic mobility is the measure of how populations and goods move over time. Geographic mobility, population mobility, or more simply mobility is also a statistic that measures migration within a population.
As the instability grows, the center of mass of the fluid is lowered. In growing waves in the atmosphere, cold air moving downwards and equatorwards displaces the warmer air moving polewards and upwards. [citation needed] Baroclinic instability can be investigated in the laboratory using a rotating, fluid filled annulus. The annulus is heated ...
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.
The medical model considers disability a physical problem: an incapability of a disabled person to perform activities of daily living like a non-disabled person. This model focuses on easing inconvenience and improving the daily experience of a person with disabilities, such as advanced assistive devices or mobility aids like wheelchairs for disabled people who live independently.
Spatial ecology studies the ultimate distributional or spatial unit occupied by a species.In a particular habitat shared by several species, each of the species is usually confined to its own microhabitat or spatial niche because two species in the same general territory cannot usually occupy the same ecological niche for any significant length of time.
Human geography (or anthropogeography) is a branch of geography that focuses on the study of patterns and processes that shape the human society. It encompasses the human, political, cultural, social, and economic aspects. Human geography can be divided into many broad categories, such as:
