The NWS is experimenting with a new graphical forecast webpage at this address: http://preview.weather.gov/graphical/
They are soliciting comments from the public on this proposed display. The new display is user friendly and can aid instructors and students. The address for comments is located on the NWS website. (13 Aug 14)
Some errors have been noted in the Weather 2012 Student Manual. See the Downloadable Material section. (07 Oct 13)
The National Weather Service has developed a new web data display. This new display is easier to use and makes available an enormous amount of data for users. This display can serve as an excellent training tool for instructors of our weather course. The site is experimental and the NWS is soliciting comments. It is intended to go active in the fall. To access, use this link: http://preview.weather.gov/edd/ (26 Jun 13)
As boaters, we are exposed to the elements from the moment we set foot on our boats. In most cases, we can anticipate and forecast inclement weather and avoid the worst. However, certain weather and oceanographic events can affect us on short notice. Our new seminar, Severe Marine Weather, attempts to identify these phenomenon to help the on the water boater to understand the event and take the appropriate action. This seminar coupled with the related Boat Handling seminars should help all boaters facing impending severe weather. Look for the new seminar later this year. (30 Jan 13)
There are a large number of applications available for smartphones and tablets related to weather. Some of these are excellent tools for on-board weather forecasting. We are creating an application list to help you determine which are useful and others that may be less so. For this we solicit your help. As you find new weather-related applications that are useful, let us know about them. We can share this information with other members. Here are some Wx apps for iOS devices and here are some Wx apps for Android devices. (30 Jan 13)
Please delete bullet number four on page 3 under slide 8. This will eliminate the confusion between the rays angle and the angle of incidence. Also, the first three bullets adequately describe the concept. (22 Apr 12)
The student and instructor kits for the revised edition of the USPS weather course began shipping in the latter part of January 2012. The new materials include a revised course manual, a new instructor manual, and an updated PowerPoint presentation. Over 2,500 copies of the Wx2008 manual have been shipped. Anticipating the need for more manuals, the course materials were revised and updated before the new Wx 2012 print run. (27 Jan 12)
A new seminar—Marine Weather Forecasting—was offered via the Internet as a webinar in June 2011. The webinar—a USPS Educational Department first—with its emphasis on the 500 mb chart and NWS sources of coastal and offshore forecasts particularly appealed to blue water cruisers. Stf/C Robert Anderson, AP, MEnvCom Assistant Chair, was the main contributor and one of the two presenters. (27 Jan 12)
A new weather seminar—Basic Weather and Forecasting—has replaced the Onboard Weather Forecasting seminar. The new seminar is more comprehensive than the superseded one (94 slides versus 63 in the old one). In addition to the Onboard Weather Forecasting QuickGuide, participants receive a full color Seminar Guide complete with notes—a major upgrade from the previous guide. There is no separate printed Instructor Guide. The notes in the Seminar Guide also serve as instructor notes. The Instructor’s CD, however, in addition to the PowerPoint presentation has a file with an Instructor’s Guide that contains suggestions and tips for instructors. (29 Apr 11)
The safety and comfort of those who venture out-on-the water have always been weather dependent. In this course students will become keener observers of the weather, but weather observations only have meaning in the context of the basic principles of meteorology — the science of the atmosphere.
The course focuses on how weather systems form, behave, move, and interact with one another and reflects the availability of all sorts of weather reports and forecasts on the Internet. Wx2012 is a general weather course benefiting those sitting in their living rooms, as much as those standing behind the helm. Each student receives:
The Weather Course is designed to be conducted over ten two-hour sessions including time for review and the multiple choice closed book exam, but each instructor will determine the pace of the course.
The Weather course manual and other materials build on a long USPS tradition of presenting a comprehensive meteorologically (scientifically) oriented course designed for recreational boaters. The 2012 Revised Edition of the course manual has both text and graphic additions and enhancements, but its basic structure and contents remain the same as the Wx2008 course.
This Instructor Manual is not the traditional black & white hard copy with all the thumbnail slide images. Instead it is a part of the instructor CD that contains the PowerPoint Presentation with slides and complete notes. Anecdotal evidence indicates that more and more instructors are not using the hard copy thumbnail images, but rather review the slides and notes using PowerPoint. The idea is to reduce costs by not printing a hard copy version. If after trying this approach, instructors still prefer a hard b/w copy with the thumbnail images, we will format and print some. Please let us know what you think after teaching the course.
Three Appendices are a part of this manual. Two of them deal respectively with Upper-Air Charts and Sounding Analysis Diagrams. Instructors should read them. They are designed to provide instructors with additional background information to increase their comfort level in teaching various topics relating to atmospheric dynamics. The third relates to Clarifications and Corrections that pertain to the original Wx2008 Course Manual, but not to the revised edition Wx2012 one. It is provided in case some students are using the Wx2008 manual. These Wx 2008 – Clarifications and Corrections also are included below on this web page.
In connection with the publication of the revised course manual, the PowerPoint presentation also has been updated with the addition of new slides and some minor changes in sequence. The revised presentation can be used with both the original and the revised course manuals.
There is an introductory set of five slides designed for use at the beginning of the first class. All the remaining slides are organized into the eight chapters of the manual. Within each chapter the slides are divided into two groups.
Wx08 /Wx12 Slide Group: The slides in the first group are designated “Wx08” or “Wx12” to indicate which slides have been added with the revised edition of the course manual. This group of integrated slides is a complete presentation of the material covered (and closely follows the organization of topics) in the chapter. The group includes figures in the manual as well as some supplemental slides. The slides begin each chapter with a title slide and a class activities/demonstrations slide—the latter being mainly for the benefit of the instructor. Most instructors will probably hide it. Each chapter presentation ends with a chapter summary.
Wx02 Slide Group: After the Wx08/Wx12 slides there is another group of slides that is designated Wx02. These “hidden” slides are legacy slides from the predecessor Wx2002 course that did not make the cut for this course. They are included only as an additional convenient resource for instructors. Unlike the Wx08/Wx12 slides, the slide notes have not been edited.
Except for some minor updating, the final examination is the same examination used with the Wx2008 Course Manual. In fact, going forward the same examination will be given to students regardless of which course manual they use. The new manual, however, contains a section of practice questions about weather scenarios. The new section comes after the Chapter 7 homework questions. Instructor’s should duplicate the Weather Scenarios section and give it to those students using the Wx2008 manual as a handout so they are not disadvantaged.
Examination Questions: The final examination is a typical 100-question USPS multiple-choice, closed-book test. About 80% of the exam questions will be based on homework questions. Unlike some of the homework questions, there will be no test questions that have the compound answers “all of the above”. The final examination will only include questions on the material in the first seven chapters. The material covered in Chapter 8 is reinforced through map drawing and analysis exercises.
Tips for the Examination: While the test will only cover the material in the first seven chapters, there is obviously some overlap in the topics dealt with in these chapters and Chapter 8 – Forecasting. If a topic is covered in one of the first seven chapters it may be on the exam even though it is also dealt with in Chapter 8. What follows are some points of clarification and some guidance for instructors and students.
Temperature Conversions: There will be no exam questions that require students to convert Fahrenheit degrees to Celsius degrees or vice versa (i.e., no questions like Chapter 1 homework questions 10 and 11 will be on the exam).
Station Models: Unlike exams for previous weather courses, station model questions will deal only with temperature, dew point, pressure, pressure tendency and wind speed and direction. There will be no questions about other symbols such as precipitation, cloud type or cloud cover. These additional station model elements are covered in Chapter 8 but only in connection with the use of the Daily Weather Maps.
Mid-Latitude Storm: Continuing a USPS weather course tradition, every exam will include verbatim the ten questions in the Chapter 6 homework based on a frontal mid-latitude storm figure (questions 20 – 29).
Scenarios: While there will be two of the customary “forecasting” scenarios on the exam (e.g., “Your cruiser is 50 miles east of….”), the analysis required to answer the three questions based on each scenario will not require any of the additional information contained in Chapter 8. Each scenario will be based upon one of the following weather events or patterns: warm front; cold front; thunderstorm squall line; advection fog; or waterspout.
A significant number of students are missing questions based on a scenario that involves a warm front pattern in the winter assuming that winter precipitation must involve a cold front. Some others are confusing an approaching warm front (indicated by a darkening sky with lowering layered–stratus-type clouds) and an approaching cold front or squall line (indicated by a line or wall of dark clouds and static or lightning).
Note that these corrections do not apply to the Revised Edition 2012 course manual. The Wx2008 course had been taught for over three years so we have the benefit of comments from instructors throughout the country. There are some substantive matters that should be clarified, refined, or corrected in the Wx2008 manual. For the most part, they are fairly technical and tangential to the main principles that are the course’s focus. Instructors should deal with them as they see fit. An errata sheet has not been included with the Wx2008 Course Manuals. Instructors should copy the corrections and clarifications that follow and give them to any students who are using the original Wx2008 course manuals rather than the new 2012 Revised Edition ones.
