Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and ...
Watercycle-french.jpg. Hydrometeorology is a branch of meteorology and hydrology that studies the transfer of water and energy between the land surface and the lower atmosphere for academic research, commercial gain or operational forecasting purposes.
An example of weather alerts on a national map from the National Weather Service. The NWS divides severe weather alerts into several types of hazardous/hydrologic events: Severe local storms – Short-fused, small-scale hazardous weather or hydrologic events produced by thunderstorms (including large hail, damaging winds, tornadoes, and flash ...
Examples of how water year is used: Used to compare precipitation from one water year to another. Used to define a period of examination for hydrologic modeling purposes. Used in reports by the United States Geological Survey (USGS) as a term that deals with surface-water supply. [2]
Winter storms can bring all sorts of precipitation: snow, sleet, hail, freezing rain or even plain old rain. Why so much variety? The answer involves temperature changes as the precipitation falls.
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
Hydrometry – the measurement of the different components of the hydrologic cycle; Chemical hydrology – the study of the chemical characteristics of water; Ecohydrology – the study of interactions between organisms and the hydrologic cycle; Hydrogeology – the study of the presence and movement of water in aquifers
For example, in a scenario where the actual temperature is 10 degrees but the "feels like" temperature is -5 degrees, what that really means is that the wind chill is making it feel as if the air ...
