    The general public has confidence in the quality and reliability of weather presentations made by broadcast meteorologists who have been certified by the AMS.

Resources and information

  • Science news to educate your audience

    Broadcast meteorologists are often the only people in television newsrooms who have a background in science.  That makes you qualified not just to deliver the weather, but also to provide more science news to your viewing audience. The AMS Station Scientist initiative helps you quickly respond to breaking news involving natural disasters, hazmat situations, and other events where a scientist can add important perspective and information to coverage of the event.  Links to instant information about these and other important subjects are readily available on the Station Scientist site.

  • Monthly newsletters

    Certification holders receive monthly ‘AMS Items of Interest’ e-newsletters filled with useful information such as professional development and networking opportunities, community involvement resources , free weather tools and graphics, and other helpful materials.

  • Social media

    AMS certification holders can discuss topics of interest and ask and give advice to each other through the AMS Certification Programs Facebook page, available only to active CBMs and Sealholders. The CBM logo may only be displayed by individuals who have earned the designation. This mark of distinction displayed on your social media sites and during your weather broadcasts sets you apart as an expert in communicating complex weather information.  

Career opportunities

  • Professional Development

    A 28 point professional development requirement every 5 years helps keep you abreast of new scientific research and tools. Attending conferences, serving as a lead forecaster on special events, mentoring a high school student, participating in a NWS workshop or a vendor sponsored training activity are just a few of the many ways to stay current in the field.

  • Networking opportunities

    Join hundreds of other broadcast meteorologist at the annual AMS Conference on Broadcast Meteorology and hear the latest research in your field. Make a presentation yourself and share your scientific knowledge and experience as a broadcast meteorologist with other attendees. Enroll in a short course in conjunction with the meeting and sharpen your skills by learning more about climate change, GOES-R and other interesting topics. Better yet, join the Board of Broadcast Meteorology, made up of other CBMs, and become an instrumental part in planning future conferences and events.

  • Career Advancement

    AMS certifications have been nationally recognized as the standard in meteorological certification since 1957 and news directors and station manager understand the high level of expertise that comes with receiving the Certified Broadcast Meteorologist (CBM) designation. Earning a CBM will set you apart from other candidates and provide you with a competitive edge.

Frequently Asked Questions

After successfully passing the multiple choice exam, applicants will receive instructions on submitting two working weathercasts for review by the AMS Board of Broadcast Meteorology with one of the submissions coming from a day on which the weather would be considered “active”; the other from a day on which the weather would be considered “routine” for the broadcast market. Off-air weathercasts will not be accepted, with the exception of those from applicants not currently employed. In this case, to better simulate the “on-air experience,” a single take with no post-production is required, and it must be recorded with current rather than archived data.

Past AMS Broadcast Board Chairs Carrie Rose and Rob Eicher offer tips and advice on the CBM weathercast evaluation.

Active Day

The definition of “active” may vary from one market to another; for instance, an “active” day in the central United States could mean thunderstorms, while an “active” day on the Pacific coast could be rain and fog, and an “active” day in the Great Lakes could mean lake effect snow. Some other examples of an active day could be involving tropical weather, a snowy morning that impacts the commute, wildfire coverage, heavy rain and flash flooding, dense fog or poor air quality. Your active day should showcase your best work on a day when a weather event will impact your viewers and may have the potential to be a threat to life and property. An active day may be when weather is the top story in the newscast.

Routine Day

A “routine” day should showcase your best work on a quiet, typical weather day. The submissions do not need to be from consecutive days; however, they must be from the time period of two months prior to the request to submit air checks, to two months after the notice.

Submitted weathercasts should be of your best work and should follow the guidelines outlined above. If submissions do not meet these guidelines, your grade will reflect any deficiencies.

Example of a Weathercast Submission Graded Favorably

The below links are examples of a weathercast submission that has met the requirements and was graded favorably by the Board of Broadcast Meteorologists. Also included are comments from the reviewers. These have been provided so that you will have a better idea of what to include in your submissions.

Reviewer comments

Review Criteria

The Board will review the submissions based on three criteria:

a) Graphical Content - This category will be used to evaluate the visual presentation and clarity in creating the proper storyline to the local weather.

b) Explanation - Reviewers are asked to determine whether or not the candidate has given scientifically valid explanation of the processes that produce the recent, current, and anticipated weather conditions

c) Presentation - This criterion is intended to measure the candidate’s ability to communicate the weather story to their audience.

A candidate must score above a 3.0 average in each category in order to succeed on the evaluation.

When the AMS receives an appeal, an Appeals Committee made up of either 3 Sealholders, CBMs, or CCMs (depending on the certification) is formed. The appeals process does not simply re-evaluate an individual's application. The appeal, to be successful, needs to show that the process failed to be followed correctly or that there were extenuating circumstances that did not allow for a fair evaluation. If the procedures were followed to the letter, and the Board fails a candidate, then that failure must stand. The Appeals Committee will not review any other material except for what was originally sent to the Board in addition to the materials outlined below. If a candidate believes that the Board did not follow the proper procedures and the evaluation was handled unfairly, he/she may appeal the decision in writing (stating the reasons for the appeal) within 90 days from the receipt of notice to the AMS Executive Committee, 45 Beacon St., Boston, MA 02108-3693. The fee to appeal is $100 (The Executive Committee reserves the right to waive the fee in cases of financial hardship.) Otherwise, candidates may wish to consider reapplying if they are eligible to do so. Requests for waivers of the waiting period to reapply may be sent to Maureen McCann, AMS Commissioner of Professional Affairs at maureen.mccann@gmail.com.

The Certified Broadcast Meteorologist (CBM) Program was inaugurated on 1 January 2005. The goal of the program is to certify that the holder meets specific educational and experience criteria and has passed rigorous testing in their knowledge and communication of meteorology and related sciences needed to be an effective broadcast meteorologist. Since the broadcast meteorologist is the primary representative of the meteorological profession to the public, we, as meteorologists, have a responsibility to help recognize those who are competent.
