AWOC Instructional Component

IC Winter 7:   Monitoring System Evolution

 

General Information

Estimated IC Completion Time
3 hours
Description
 This IC provides instruction on how to monitor system evolution using real time data and model information to produce short term forecasts and warning updates for winter weather. The process discussed in this IC involves interpreting the accuracy of model analysis, radar precipitation estimates, snow spotter information, surface observations, and web cams.
Testing Procedures
Testing for Instructional Components (IC) lessons is provided to the student using the NWS Learning Management System (LMS). If testing is required, the test must be successfully completed in order to complete the lessons. A score of at least 70% on the exam is required to successfully complete each lesson.

Lessons
Lesson 1:

Monitoring Model Accuracy

Description
 This lesson describes the benefits of diagnosis of observations contrasted with some of the pitfalls of numerical weather prediction for winter weather. Pete Banacos (Forecaster, NWS APX), and Dan Bikos (CIRA) produced this lesson. Note: As the lesson proceeds, click the "show URL" button when it is active to take the interactive quizzes.

Lesson 2:

WSR-88D Winter Weather Precipitation Estimation

Description
 Part 1 of this lesson illustrates where the radar overestimates precipitation due to various situations such as: overshooting, brightbanding, sub-beam evaporation, and horizontal drift. The lesson also shows how precipitation particle shape affects radar reflectivity. Part 2 of this lesson shows how the process of analyzing radar errors due to overshooting and bright-banding are exemplified via a case study. Jim LaDue (NWS WDTB) produced this lesson.

Lesson 3:

Effective Use of Spotters and Webcams

Description
 This lesson, produced by Carl Dierking (SOO, NWS JNU), shows how to identify spotter and webcam sources and their associated strengths and weaknesses. The lesson also discusses the considerations in using these types of uncontrolled data sources and the process of how forecasters might use this information in the warning process by improving situational awareness.

Lesson 4:

Diagnosing Unexpected Precipitation Areas

Description
 This lesson demonstrates a methodology for recognizing and responding quickly and decisively to unexpected precipitation by improving the forecast. Produced by Bruce Smith (SOO, NWS APX), the lesson emphasizes the role of using observational data utilizing effective diagnosis and short term forecasting techniques. After a methodology of 5 basic steps is presented, a case study is shown to apply the methodology.
