Interpreting and Communicating EPS Guidance: Germany Winter Event
This 45-minute lesson briefly introduces learners to the benefits of using probabilistic forecast information to assess weather and communicate forecast uncertainties. Learners will explore a winter weather event in Germany and practice synthesizing deterministic and probabilistic forecast guidance to better understand forecast uncertainties based on lead-time. Also, learners will decide how to best communicate the potential weather threats and impacts to local end users. The lesson is another component of the Forecast Uncertainty: EPS Products, Interpretation, and Communication distance learn ...
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.
Communicating Winter Weather Surface Impacts
This lesson will introduce National Weather Service (NWS) forecasters to the benefits of pre-season coordination in understanding the critical needs of decision-makers, particularly the state and local Departments of Transportation (DOTs). The strategies used by DOTs to mitigate road impacts during the winter and how the NWS can best support their needs are also discussed. Learners will gain insight into the common methods of collaboration between the NWS and DOT, and the different types of winter weather events in which they work together. Learners will also practice communicating winter weat ...
Weather Decision Support for the National Airspace System
This three-hour lesson describes the impacts of weather on aviation operations and highlights the role of the National Weather Service (NWS) in supporting the Federal Aviation Administration's air traffic management organization. The lesson contains an Introduction (40 min), several cases (10-20 min each) focused on various weather phenomena, and a detailed case (35 min) allowing forecasters to follow the planning for and evolution of an event. The content emphasizes best practices for aviation forecasters, including identifying and communicating the threat, understanding partners' needs, and ...
Remote Sensing Using Satellites, 2nd Edition
The second edition of the popular "Remote Sensing Using Satellites" module updates imagery of recent hurricanes as well as other phenomena from more recent satellites. The suggested audience for this module is high school and undergraduate students. Learn about remote sensing in general and then more specifically about how it is done from satellites. We will focus on the visible and infrared channels, those commonly seen on television broadcasts. Come explore the view of Earth from space and see what we see. In the second chapter, we will focus even more on hurricanes and specifically Hurrican ...

Assessing the Impacts of Eurasian Snow Conditions on Climate Predictability with a Global Climate Model
On the basis of two ensemble experiments conducted by a general atmospheric circulation model (Institute of Atmospheric Physics nine-level atmospheric general circulation model coupled with land surface model, hereinafter referred to as IAP9L_CoLM), the impacts of realistic Eurasian snow conditions on summer climate predictability were investigated. The predictive skill of sea level pressures (SLP) and middle and upper tropospheric geopotential heights at mid-high latitudes of Eurasia was enhanced when improved Eurasian snow conditions were introduced into the model. Furthermore, the model ski ...

Interannual Variability of Snow Depth over the Tibetan Plateau and Its Associated Atmospheric Circulation Anomalies
The interannual variability of wintertime snow depth over the Tibetan Plateau (TP) and related atmospheric circulation anomalies were investigated based on observed snow depth measurements and NCEP/NCAR reanalysis data. Empirical orthogonal function (EOF) analysis was applied to identify the spatio-temporal variability of wintertime TP snow depth. Snow depth anomalies were dominated by a monopole pattern over the TP and a dipole structure with opposite anomalies over the southeastern and northwestern TP. The atmospheric circulation conditions responsible for the interannual variability of TP s ...

Avalanche Weather Forecasting
Avalanches form through the interaction of snowpack, terrain, and weather, the latter being the focus of this module. The module begins with basic information about avalanches, highlighting weather's role in their development. The rest of the module teaches weather forecasters how to make an avalanche weather forecast, that is, one in which key weather parameters are evaluated for their impact on avalanche potential. The forecasts are used primarily by avalanche forecasters, who integrate them with other information to determine when to issue avalanche hazard warnings. The module contains five ...
Snowpack and Its Assessment
This module explores the science of snowpack and snowpack assessment. It begins by describing the factors involved in snowpack development and then focuses on snowpack evolution. Using two scenarios (one set in mountainous terrain, the other in a relatively flat area), the module explores how basic processes, such as conduction and radiation, and various precipitation events impact snowpack, particularly its density, structure, and stability, throughout the cold season. Woven throughout the module are video clips of avalanche forecasters discussing snowpack and demonstrating various assessment ...
Weather and Road Management
Anticipating and dealing with weather and the hazards it creates is a real challenge for those in departments of transportation. This module gives road and highway managers a basic understanding of meteorology and weather hazards so that they can better interpret weather forecast information used to make road management decisions. The module also highlights web-based forecast products available from the National Weather Service that can help in the decision-making process.
