CAMEO is a system of software applications used widely to plan for and respond to chemical emergencies. It is one of the tools developed by EPA’s Office of Emergency Management (OEM) and the National Oceanic and Atmospheric Administration Office of Response and Restoration (NOAA), to assist front-line chemical emergency planners and responders.
The HYSPLIT model can be run interactively on the Real-Time Environmental Applications and Display System (READY) web site [12] or installed on PC, Mac, or Linux applications, which use a graphical user interface, or automated through scripts ('PySPLIT' package in Python, 'openair' and 'splitr' packages in R). HYSPLIT is rather unusual in that ...
The Rapid Refresh is run at the NOAA National Centers for Environmental Prediction (NCEP). It is based on the framework of the Weather Research and Forecasting model (WRF); the Global Forecast System (GFS) provides the boundary parameters. The grid points are spaced every 13 kilometres (8.1 mi), with 50 vertical intervals extending up to the 10 ...
NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this. WRF features two dynamical (computational) cores (or solvers), a data assimilation system, and a software architecture allowing for parallel computation and system extensibility. The model serves a wide range of ...
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
On NOAA's HeatRisk tool, the scale ranges from 0 or green, meaning little or no risk from expected heat, to 4 or magenta, which indicates extreme and/or long-duration heat-related impacts.
Marestail shows moisture at high altitude, signalling the later arrival of wet weather. Along with pressure tendency, the condition of the sky is one of the more important parameters used to forecast weather in mountainous areas. Thickening of cloud cover or the invasion of a higher cloud deck is indicative of rain in the near future.
