In addition, critical fire weather patterns are described in terms of their development, duration and impact on fire weather. Numerous case studies provide examples and opportunities to practice recognizing these critical patterns and how they can affect fire ignition and spread.

Watersheds: Connectiong Weather to the EnvironmentFire Behavior (April/08)

This module provides a comprehensive overview of the three main dimensions of the fire environment triangle: fuels, topography, and weather. Five interactive case studies illustrate the interdependent influences these three dimensions have on fire behavior. A wide range of fire behavior is also discussed in terms of the environmental factors that support or suppress fire ignition and spread.

Antarctica: Challenging Forecasts for a Challenging EnvironmentAntarctica: Challenging Forecasts for a Challenging Environment (Summer/07)

Dwight designed and developed the 10-minute Overview Section of this 2-part publication created to support outreach and training efforts for the 2007-2008 International Polar Year.

Antarctica is a fascinating and challenging environment to study. Starting with the early explorations more than 200 years ago to present-day field research, we’ve learned a lot. But there is a great deal more we need to discover, particularly if we are going to be able to understand climate change on this planet.


Watersheds: Connecting Weather to the EnvironmentWatersheds: Connecting Weather to the Environment (August/06)

This short course provides broadcast meteorologists with knowledge and instructional materials to help them understand watersheds as our environmental home and to help their viewers understand the relationship between the weather and the health and protection of the environment.

Environmental impacts in many areas of the country result from the daily actions of people. We can easily see the consequences of a major oil spill at sea that is driven ashore by winds and ocean currents, but what about the fertilizer that people put on their lawns and the de-icer they apply to their driveway, or changing the car’s oil in the backyard, or the pet waste in the yard or local park? Combined with weather, all of these have an impact on both the local environment and the larger regional environment.

Shallow-Water WavesShallow-Water Waves (August/06)

As deep-water waves approach the coastline, they encounter shallower water and begin to interact with the sea floor while evolving into shallow water waves. This
module uses an interactive wave calculator to look at a variety of shallow-water wave behaviors, including shoaling, refraction, reflection, breaking, attenuation, and coastal run-up and set-up. All are important considerations when forecasting for small craft and other recreational interests in the near-shore environment.

Hurricane Strike!Hurricane Strike! (December/04; April/02)

Designed primarily for middle school students and funded by FEMA and the NWS, this module creates a scenario to frame learning activities that focus on hurricane science and safety.

Over the course of seven days, Hurricane Erin forms in the Atlantic Ocean, crosses the Florida peninsula, and then makes another landfall at Fort Walton Beach. During these days, the learner is introduced to many basic concepts of atmospheric science, climate, and geography, while also learning some important and possibly life-saving safety and preparedness skills. The module includes several interactive games and activities that address hurricane meteorology and hurricane safety.

Teachers and others who use the module for public education will find the "Information for Teachers" section particularly useful. This section provides information about all of the main learning objects in the module, as well as access to them as stand-alone activities. Links to numerous hurricane-related Web sites are also included, as are links to expert advice about helping children deal with trauma. Worksheets that test the learner's understanding of the module's content are provided in this section, as well as throughout the module. Versions are also available for Spanish-language students and for hearing, motor, and visually impaired students.

This project received the 2004 American Meteorological Society’s Louis J. Batton Authors Award for “outstanding, newly published learning materials..that foster the understanding of atmospheric and related sciences in K-12 audiences.” The site has also earned top rating at Surfing the Net with Kids.

This module includes numerous practice exercises allowing learners to improve their skills in icing assessment using these basic observational tools.

Icing AssessmentAviation Icing Assessment Using Soundings and Wind Profiles (November/98)

This module teaches how to assess vertical profiles of wind, temperature, dewpoint, and frost point in order to diagnose airmass characteristics, cloud layers, and possible aviation icing layers. Topics include strengths, weaknesses, and appropriate uses of rawinsonde and profiler data for assessment of aviation icing, icing characteristics of the different extratropical cyclone air masses, identification of dry and saturated layers and possible zones of favorable conditions for aircraft icing, and ice seeding and glaciation processes.

This module was built as a hybrid Web/CD application, requiring use of a companion CD-ROM called The Icing Event of 6 March 1996.

Forecasting Aviation IcingAviation Icing Type and Severity (March/98)

This module discusses the current theories of atmospheric conditions associated with aircraft icing and applies the theories to the icing diagnosis and forecast process. The contribution of liquid water content, temperature, and droplet size parameters to icing are examined. Identification of icing type, icing severity, and the hazards associated with icing features are presented. Tools to help diagnose atmospheric processes that may be contributing to icing and the special case of supercooled large drop (SLD) icing are examined and applied in short exercises.

The Headwater Forecast Process

Hydrology for the Meteorologist: The Headwater Forecast Process (1998)

This on-line course covers the basic procedures involved in evaluating a potential headwater flooding situation to determine if the public needs to be alerted. The different types of products needed to make these decisions are introduced and interactions are provided to allow you to practice using them. The decision-making process is incapsulated in an included Web-based hypertext decision aid for headwater forecasting.

As you move through the headwater forecast process, you must employ the concepts learned in Hydrology for the Meteorologist: Basic Hydrology for Headwater Forecasting in order to make decisions about issuing a flood product. Being aware of how a runoff event will affect the basin of interest will allow you to focus on the regions most likely to experience flooding.
