Strategies for responding to climatic change that reduce the consequences of the changing climate by adjusting the physical environment or the interactions between the environment and human society.
Industry:Weather
A grid on which the number or geometric distribution of points changes in response to the characteristics of the evolving flow that is being described. Adaptive grids are most commonly used to place higher resolution in regions where error is likely to be large, for instance, in areas where the gradient (or Laplacian operator) is large.
Industry:Weather
An observational network in which the location and timing of measurements of atmospheric properties are changed on a daily basis in order to minimize some measure of forecast error. To achieve this aim, atmospheric measurements must adapt to the flow observed on a particular day. For example, in midlatitude regions, enhanced atmospheric measurements in regions of large horizontal temperature gradients can lead to a significant reduction in forecast error. As these regions of strong baroclinicity move from one day to the next, the locations of enhanced measurements should also move.
Industry:Weather
Observational data obtained specifically to improve model initial conditions for a numerical forecast of a selected weather feature, or to optimize a measure of forecast outcome (e.g., error). Guidance for selecting adaptive observations can be obtained from model-based products, such as singular vectors from adjoint models or ensemble forecasts, which are used to estimate where initial condition error has the greatest impact on the forecast measure. Adaptive observations can be obtained from in-situ platforms such as dropsonde aircraft, or by direction of remote sensors including satellite or radar instruments. See adjoint model, adjoint sensitivity.

Industry:Weather
The process by which one object becomes adhered to another by the binding action of ice.
Industry:Weather
In cloud physics, the fraction of ice particles colliding with a collector ice particle that actually adheres to, or aggregates with, the collector; or, in the case of the riming process, the fraction of water drops colliding with a collector ice particle that actually adheres (freezes) to the collector.
Industry:Weather
The adhesion of a thin film of liquid or gas onto a solid substance. The solid does not chemically combine with the adsorbed substance. See sorption; compare absorption.
Industry:Weather
The slope (usually equatorward, or southward in the Northern Hemisphere) of a mountain that faces into the sun. The term is originally and most often used in referring to mountains in the Alps. Tilted toward the sun, an adret is characterized by higher temperatures, a longer growing season, less snow cover and a shorter duration of snow cover, and a higher timber line and snow line than the shaded side (the ubac).
Industry:Weather
Upper limit of concentration of a substance in water that is deemed not harmful. The definition of harmful substance is regulatory dependant.
