Met 101: Basic Weather Processes
This lesson provides an overview of basic weather processes, beginning with how the distribution of incoming solar energy helps to establish Earth’s atmospheric circulations. Learners will gain an understanding of the differences between weather and climate, and how Earth’s winds tend to have dominant patterns determined by region. An introduction to atmospheric stability, clouds, precipitation processes, and thunderstorm characteristics is also included, along with an introduction to weather impacts affecting aviation operations.

GOES-R Series Faculty Virtual Course: Aviation Products
In this webinar recording, Amanda Terborg (with input from Dr. Chad Gravelle), will demonstrate the capabilities of GOES-R/16 in analyzing hazards affecting the aviation industry. The talk focuses specifically on four hazards (but there are others): 1) fog and low stratus, 2) in-flight turbulence, 3) dust, and 4) volcanic ash. Through the use of GOES-R/16 spectral bands, band differences, and RGB composites, satellite data users can detect the development and evolution of aviation threats better than with any previous geostationary satellites. This is a recorded webinar presented by an instruc ...

Forecasting Mountain Wave Turbulence for Aviation
Turbulent flow that impacts aviation can be caused by several different factors and can occur at both low and high-levels in the atmosphere. This lesson focuses on forecasting mountain wave turbulence. Its methodology relies on the spatial and temporal distribution of winds, stability, and clouds to forecast and verify mountain wave turbulence. Analyzed forecast products include NWP charts, cross sections and soundings, satellite imagery, RAOBs, PIREPS, and graphical turbulence guidance (GTG). The lesson is targeted for aviation forecasters at the U.S. National Weather Service (NWS). The modul ...

Forecasters' Overview of the Mediterranean and Europe
This module provides an introduction to the European continent and the Mediterranean and Black Sea areas for weather forecasters. It focuses on geography, climatology, oceanography, major aspects of the synoptic and mesoscale weather patterns, and hazards to aviation and maritime operations. Geography covers major political boundaries, cities, ports, topographical features, rivers, and volcanic areas. Climatology covers the seasonal climatology of jet stream, synoptic weather systems, extratropical cyclones, and high winds and seas. Oceanography includes major bathymetric features; mean sea su ...

Predicting Convective Cessation for Aviation Forecasters
This module introduces aviation forecasters to a conceptual framework for analyzing, diagnosing and predicting convective cessation and resulting conditions near airports. Users will first learn about five main environments with respect to convection, and three patterns in which these environments are commonly arranged. Next, users are immersed into an adjustable-time case simulator to practice applying the convective environment frameworks to their forecast process, while periodically amending TAFs and responding to warning, storm report and caller interruptions. Finally, a case summary ties ...

GOES-R ABI: Next Generation Satellite Imaging
This extension of the COMET lesson “GOES-R: Benefits of Next Generation Environmental Monitoring” focuses on the ABI instrument, the satellite's 16-channel imager. With increased spectral coverage, greater spatial resolution, more frequent imaging, and improved image pixel geolocation and radiometric performance, the ABI will bring significant advancements to forecasting, numerical weather prediction, and climate and environmental monitoring. The first part of the lesson introduces the ABI's key features and improvements over earlier GOES imagers. The second section lets users interactively ex ...

Scale-by-scale analysis of probability distributions for global MODIS-AQUA cloud properties: how the large scale signature of turbulence may impact statistical analyses of clouds
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. de la Torre Juárez M.; Davis A.B.; Fetzer E.J. - Copernicus GmbH, 2011Means, standard deviations, homogeneity parameters used in models based on their ratio, and the probability distribution functions (PDFs) of cloud properties from the MODerate resolution Infrared Spectrometer (MODIS) are estimated globally as function of averaging scale varying from 5 to 500 km. The properties – cloud fraction, droplet effective radius, and liquid water path – all matter for cloud-climate uncertainty quantification and reduction efforts. Global means and standard deviations are confirmed to change with scale. For the range of scales considered, global means vary only within 3% ...

Forecasting Dust Storms - Version 2
Forecasting Dust Storms Version 2 provides background and operational information about dust storms. The first part of the module describes dust source regions, the life cycle of a dust storm, and the major types of dust storms, particularly those found in the Middle East. The second part presents a process for forecasting dust storms and applies it to a case in the Middle East. Although the process refers to U.S. Department of Defense models and tools, it can easily be adapted to other forecast requirements and data sources. Note that this module is an updated version of the original one publ ...

Influence of Model Physics on NWP Forecasts - version 2
This module, part of the "NWP Training Series: Effective Use of NWP in the Forecast Process", describes model parameterizations of surface, PBL, and free atmospheric processes, such as surface snow processes, soil thermal and moisture processes, surface vegetation effects such as evapotranspiration, radiative processes involving clouds and trace gases, and turbulent processes in the PBL and free atmosphere. It specifically addresses how models treat these processes, how such processes can potentially interact with each other, and how they can influence forecasts of sensible weather elements. B ...
