Click on the panels below to access the content for each topic of the course. For most lessons, there will be two ways to access the training materials:

  • Web Version - Lesson streams from the WDTD web server & doesn't require login; or
  • LMS Version - Links to NWS Learning Center (aka: LMS) so NWS employees can get completion credit, but login is required to access

The lesson content is the same for each link. NWS employees enrolled in the RAC should use the LMS Version in link to ensure they receive completion credit. We have a RAC handout PDF available to print out that contains the slides and speaker notes for most lessons. There are also handouts available for each topic in the collapsible panels below with built in navigation for web viewing.

Orientation

Brief Description: This lesson provides an overview of the course to students and local facilitators. Each section of the course will be touched
Delivery Method: Teletraining
Approximate Completion Time: 1 hour

Content:

AWIPS Fundamentals

Brief Description: The AWIPS Fundamentals pre-requisite for RAC uses an intro presentation on the Web, web pages with job sheets in the VLab (accessible from your live AWIPS), WES-2 Bridge exercises, and a locally-proctored Proficiency Exam.
Delivery Method: Web presentation, web pages accessible from your local AWIPS, videos on WES-2 Bridge

Introduction to the WSR-88D System

Brief Description: This lesson is an overview of all of the main components and subcomponents of the WSR-88D system. In order to effectively operate the system and produce the best quality data, it is important to understand the basics of these six components and how data flows through the entire system.
Delivery Method: On-line Training Module
Approximate Completion Time: 1 hour

Content:

Principles of Radar

Brief Description: This topic consists of 24 lessons that cover a variety of scientific principles about how Doppler radar in general, and the WSR-88D in particular, work. These lessons will cover many technical details of how the WSR-88D collects data, quality controls it, and processes it into base and derived products.
Delivery Method:Asynchronous instructor-led web modules
Approximate Completion Time: 9 hours

Content:

Velocity Interpretation

Brief Description: This topic consists of two lessons on the proper interpretation of radial Doppler velocity patterns. These lessons will present how to interpret Doppler velocity patterns under uniform, non-uniform, ambiguous, and meteorologically complex conditions.
Delivery Method: Asynchronous instructor-led web modules
Approximate Completion Time: 90 minutes

Content:

Base and Derived Products

Brief Description: This topic will present the suite of Base and Derived Products and their applications. Also presented will be relevant information on the algorithms that generate the various products and displays.
Delivery Method: Asynchronous instructor-led web modules and Teletraining
Approximate Completion Time: 12-14 hours

Content:

Base Products (Part 1)

Reflectivity Derived Products (Part 2)

Velocity Derived Products (Part 3)

Dual-Polarization Derived Products (Part 4)

Precipitation Estimation Products (Part 5)

Winter Weather Applications

Brief Description:This topic covers winter weather precipitation type analysis and how to account for errors in the Snow Accumulation Algorithm (SAA).
Delivery Method: On-line training modules
Approximate Completion Time: 1 hour

Content:

Convective Storm Structure and Evolution

Brief Description: This topic describes some important thermodynamic and kinematic parameters developed to evaluate convective severe weather potential. The instruction also treats the fundamental relationships between shear and instability with respect to convective storm type, focusing both on recent observations and numerical simulations of storms. Next are typical environments of weakly sheared and strongly sheared convection, recognition and interpretation of severe storm signatures, and how severe weather signatures are manifested by particular severe weather hazards.
Delivery Method: On-line web module and asynchronous instructor-led web modules
Approximate Completion Time: 10 hours

Content:

Flash Floods

Brief Description: This topic introduces the fundamental concepts behind flash flood meteorology and hydrology. Additionally, it discusses the products and tools available in AWIPS-2 that can be useful for flash flood decision-making.
Delivery Method: asynchronous instructor-led web modules
Approximate Completion Time: 3 hours

Content:

Storm-Based Warning Fundamentals

Brief Description: This topic provides the fundamental knowledge and skills required to issue effective storm-based warnings. Training includes skills for basic proficiency in using some AWIPS storm interrogation applications such as WarnGen, and recommended strategies for polygon creation and placement.
Delivery Method: WES-2 Bridge exercises (tracked on CLC transcript), asynchronous instructor-led web modules, and teletraining
Approximate Completion Time: 11 hours

Documentation: Storm-Based Warning Fundamentals Handout
RAC Workshop

Brief Description: This workshop is a five day in-residence training that completes RAC. This workshop, which is held at the National Weather Center (in Norman, OK), gives RAC students the opportunity to apply the content they learned about in the previous seven topics during a variety of exercises and simulations, as well as participate in several presentations about current and future operational applications, tools, and research.
Delivery Method: In-Residence Workshop
Approximate Completion Time: 40 hours (5 days)
