Typically, this process involves predicting the shape of a hydrograph downstream from a particular location in a channel, reservoir, or lake. This first requires an understanding of the basic flow regimes and how water is stored and released within a channel. From there, information and calculations based on flow and channel bed characteristics are implemented in hydrologic routing methods, which are storage-based, and hydraulic routing methods, which utiliz ...PermalinkTurbulence is a major concern for the aviation industry. It often goes undetected in cloud-free areas, catching pilots off guard when they fly into it. Turbulence can injure passengers and crew, and cause structural damage to aircraft. This makes it critical for aviation weather forecasters to closely monitor the atmosphere for signs of turbulence and issue special warnings when it is likely to be present. This lesson helps prepare forecasters for these tasks by providing general information about turbulence and showing them how to detect it using satellite imagery, tephigrams, and NWP product ...PermalinkThis interactive case exercise covers a 24-hour forecast period that includes the challenge of precipitation type forecasting. The case exercise provides an overview of precipitation type forecasting based on model algorithms, partial thickness analysis, and the top-down method.PermalinkThis module provides a comprehensive overview of the three main dimensions of the fire environment triangle: fuels, topography, and weather.
