2 Webinars Eumetcal per il corso “High Impact Weather”

Nell’ambito del corso High Impact Weather, Rob Groenland (KNMI) presenterà due webinars il mese prossimo:

  1. Mercoledi 12 April 2023 alle ore 08:00 UTC /10:00 AM CEST, é possibile registrarsi al seguente link
  2. Martedi 9 Maggio alle ore 08:00 UTC /10:00 AM CEST, é possibile registrarsi al seguente link

Si ricorda che le registrazioni sono gratuite e aperte a tutti. Maggiori dettagli sul corso High Impact Weather di seguito:

This HIW course is an online course for EUMETCAL and will focus on the use of a particular forecasting method based on Doswell’s ingredient-based forecasting method IBM (1996). This method assumes that three ingredients are needed for convection: moisture, lift, instability (and vertical wind shear to take the modes in convection into account).

These convection modes each have their own distinctive characteristics as regards duration, radar images and, in particular, hazardous weather phenomena (lightning, wind gusts, hail and heavy precipitation). This method has been incorporated into a convection scheme that is currently used at the KNMI forecasting office; it leads, via a few steps, to one of four convection modes. This online course e.g. explain the method and describe a number of typically synoptic situations that yield severe convection with some regularity.

The use of the convection prediction scheme in forecasting convection leads to a better physical understanding of convection, more objective forecasting methodologies and more accurate forecasts of hazardous weather phenomena. The convection prediction scheme can be used to make a good assessment of the probability of hazardous weather phenomena. The latter are rare in the case of single cells, for example, whereas pulse storms are frequently accompanied by strong downdrafts (wind gusts) and heavy precipitation and supercells are infamous for their prolonged duration, large hail, strong lightning activity and wind gusts.

Key goals: The goal of this online course is to help forecasters in forecasting of deep summertime convection with the help of this IBM.

  • Improve the forecast of deep summer convection with the help of a scheme to determine where and what type of convection can be forecasted Improve the forecast of the related hazardous weather

Why the training is important for our organization (KNMI) and other NMS’s in Europe: Due to some missed forecasts of deep convection in the past we started to use this methodology (and corresponding convection scheme) in 2014 at KNMI.

Note: After the course was concluded in 2021, it was made available to the community as a standalone time-independent learning material.

New in 2023: Rob will hold two more webinars as a followup to the learning material. They will be held on 12 April and 9 May 2023. Register here.

Recordings of the webinars are available inside Moodle environment.
Expected Learning Outcomes

After completing the training, participants will be able to:

  • Determine where and when deep convection will be initiated based on the convection scheme (IBM); they have to found the overlap regions of moisture, instability and lift.
  • Determine which mode of convection can be expected; single cell/ pulse cell, multi cell, squall line or supercell
  • Determine the corresponding hazardous weather

Target Audience / Copyright

Primary audience: forecasters working in the operation office of the National Weather Service or Meteorological Centres in Europe. The participants are expected to already have a basic experience in forecasting summer convection.

Secondary audiences: meteorologists interested in synoptic and mesoscale phenomena (related to summer convection), involved in training, research or management, who would benefit from the course and also provide necessary feedback.

EUMETCAL – High Impact Weather Webinars

EUMETCAL ha annunciato che si terranno nei giorni 11 aprile e 2 maggio due webinar dal titolo “High Impact Weather”.

I webinar seguono il corso HIW offerto da EUMETCAL nel 2021.

L’obbiettivo di questo corso è quello di fornire un supporto ai previsori nella previsione delle convezioni profonde estive attraverso l’ausilio dell’IBM (Doswell’s ingredient-based forecasting method).

L’evento è aperto principalmente ai meteorologi che operano nei servizi meteorologici nazionali o nei centri meteorologici in Europa. Ci si aspetta che i partecipanti abbiano già un’esperienza di base nella previsione delle convezioni estive.
