Gravity for Geodesy I: Foundations
The first of a two-part series, this 40-50 minute non-narrated interactive lesson is intended to help professionals with basic science background better understand the Earth’s gravity field and what causes its variations. Of particular interest to earth/physical scientists as well as surveying engineers, this lesson covers Newton’s laws with a focus on Earth’s gravity field as it applies to geodesy. After a review of the basics of Newtonian gravitation and gravity, it explores how density, altitude, and latitude affect gravity.
Low-Level Coastal Jets
Low-level coastal jets occur along many coastlines. Winds may exceed 35 knots and lead to high waves and significant low-level vertical wind shear. Thus, low-level coastal jets present a hazard to both marine and aviation operations in the coastal zone. This core module describes the features of coastal jets and explores the conditions under which they form. Like other foundation modules in the Mesoscale Primer, this module starts with a forecast scenario and concludes with a concise summary and a final exam. By the end of this module, you should have sufficient background to diagnose and fore ...
Fire Weather Forecasting: Clear Communications, Second Edition
This lesson will introduce National Weather Service (NWS) forecasters to the communication strategies used for decision support services during wildland fire incidents. It also serves as a baseline for practices that leverage unique NWS capabilities to assist land management, firefighting, and emergency management entities in critical decision making. The learners will work through a simulation to see the effects of their communication choices on decisions made by fire personnel. The lesson replaces an earlier edition produced in 2008.
Gap Winds
This lesson provides a basic understanding of why gap winds occur, their typical structures, and how gap wind strength and extent are controlled by larger-scale, or synoptic, conditions. You will learn about a number of important gap flows in coastal regions around the world, with special attention given to comprehensively documented gap wind cases in the Strait of Juan de Fuca and the Columbia River Gorge. Basic techniques for evaluating and predicting gap flows are presented. The lesson reviews the capabilities and limitations of the current generation of mesoscale models in producing realis ...
S-290 Unit 2: Topographic Influences on Wildland Fire Behavior
S-290 Unit 2: Topographic Influences on Wildland Fire Behavior provides an overview of how topography affects fuels and the direction and spread of wildland fires. Information on features of topographic maps and estimating slope is also presented. This module is part of the Intermediate Wildland Fire Behavior Course.
The Role of the MJO in Oceanic and Atmospheric Variability
This Webcast, presented by Dr. Klaus Weickmann of NOAA/CIRES/Climate Diagnostic Center, explores the role that the Madden-Julian Oscillation (MJO) plays in global climate variability. The expert lecture is divided into five sections, which give a short overview of the phenomenon, discuss its relationship with sea surface temperatures, compares composite MJO events to individual occurrences, and touches on the ability of models to predict MJO events.
SatFC-J: The AMSR2 Microwave Imager
This short lesson describes the Advanced Microwave Scanning Radiometer 2 (AMSR2) on board the next-generation polar-orbiting satellite platforms. AMSR2’s primary mission is to improve scientists’ understanding of climate by providing estimates of precipitation, water vapor, cloud water, wind velocity, sea surface temperature, sea ice concentration, snow depth, and soil moisture. AMSR2 also advances weather forecasting through real-time imagery, value-added products, and input to numerical weather prediction. This lesson is part of the Satellite Foundational Course for JPSS (SatFC-J).
Downscaling of NWP Data
Forecasters utilize downscaled NWP products when producing forecasts of predictable features, such as terrain-related and coastal features, at finer resolution than provided by most NWP models directly. This lesson is designed to help the forecaster determine which downscaled products are most appropriate for a given forecast situation and the types of further corrections the forecaster will have to create. This module engages the learner through interactive case examples illustrating and comparing the major capabilities and limitations of some commonly-used downscaled products for 2-m tempera ...
Satellite Foundational Course for GOES-R: SatFC-G (SHyMet Full Course Access)
The Satellite Foundational Course for GOES-R (SatFC-G) is a series of nearly 40 lessons designed specifically for National Weather Service (NWS) forecasters and decision makers to prepare for the U.S.’ next-generation geostationary environmental satellites. The course is intended to help learners develop or improve their understanding of the capabilities, value, and anticipated benefits from the GOES-R suite of instruments. These instruments and imagery offer improved monitoring of meteorological, environmental, climatological, and space weather phenomena and related hazards. The course will a ...
Tropical Mesoscale Convective Systems
Mesoscale Convective Systems (MCSs) occur globally and can account for significant percentages of the annual precipitation in some locations. MCSs are responsible for flooding as well as damaging surface winds in some instances. Thus, it is important for forecasters to understand when, where, and how MCSs develop and maintain themselves. This module covers all modes of MCSs with a strong focus on the tropics and the different aspects that brings to MCS development, maintenance, and structure. It describes conceptual models of MCSs and the dynamical and physical processes that influence their e ...
Forecasting Sensible Weather from Water Vapour Imagery
Forecaster nowcasting at the synoptic scale is rapidly being replaced by the numerical weather prediction models. However, there are plenty of opportunities for you as a forecaster to improve on those forecasts with simple comparisons of water vapour hand analyses and surface hand analyses. The goal of this lesson is to improve your skills in water vapour and surface analyses to evaluate the three-dimensionality of the atmosphere and thus forecast the sensible weather better. This is the capstone for the entire Satellite Interpretation distance learning course.
Fog and Stratus Forecast Approaches
This module deals with identifying the characteristics of radiation versus advection fog events, determining which process is dominating, and applying that understanding when making ceiling and visibility forecasts. A forecast approach using a decision tree is also discussed. This decision tree outlines the basic steps involved in applying a thorough forecast approach to fog and stratus events. The module is based on live teletraining sessions offered in 2003 as part of the Distance Learning Aviation Course 1 (DLAC1) on Fog and Stratus Forecasting.
Wave Life Cycle I: Generation
This is the second in a series of training lessons on marine wind and waves. The first lesson discussed wave types and characteristics and is a good primer to this next marine training topic. Wave Life Cycle I: Generation examines how wind creates waves and the inter-relationships between wind speed, wind duration, and fetch length during this process. These three factors are important to predicting wave height and what will limit wave growth. Additional topics include fully developed seas, observation sources, and various special wind events such as coastal jets and instability mixing in the ...
Alberta Clipper Case Exercise
This case study focuses on a snow and blowing snow event in the Canadian prairies and US northern high plains on 11-13 November 2003. The key aim of this module is to step through the forecast process during an Alberta Clipper event from the perspective of a forecaster with the Meteorological Service of Canada. This involves consideration of various observations and model guidance, identification of potential areas of snowfall and blowing snow, nowcasting snowfall development and termination, and considering and providing nowcast updates throughout.
SatFC-J: The VIIRS Imager
This lesson introduces the VIIRS imager on board the Suomi NPP and JPSS satellites. The lesson briefly describes the capabilities, improvements, and benefits that VIIRS brings to operational meteorology. Numerous images are shown that demonstrate a variety of applications available in the AWIPS weather display system. This lesson is part of the Satellite Foundational Course for JPSS (SatFC-J).
