This Webinar was delivered by Mr. Tim Hewson and recorded in February 2015. The process by which extra tropical cyclones are identified and tracked in the ECMWF IFS analyses and forecasts will be described, and this will be followed by an overview of the multi-faceted web products that relate, and how to use them. Reference will also be made to objective fronts.

This Webinar was delivered by Dr. Richard Forbes and recorded in February 2015. This seminar will describe how cloud and precipitation is represented in the ECMWF global model with examples of model evaluation against different types of observations and strengths and weaknesses highlighted. The cloud related forecast products are discussed with some insights into interpretation in different meteorological situations. By the end of this seminar you should be able to: 1. Describe how cloud and precipitation is represented in the ECMWF global model 2. Recognise some of the strengths and weaknesses of the forecast cloud/precipitation. 3. Interpret cloud and precipitation related forecast products.

This Webinar was delivered by Dr. Linus Magnuson and recorded in February 2015. The aim the lecture is to give a motivation for why ECMWF produces a data set for the model climate, explain the configuration of it and discuss some of the strengths and weaknesses (limitations). In the lecture we will also explain the cumulative distribution function of the model climatology, as a background for the extreme forecast index (EFI).

This webinar was delivered by Dr. Mark Rodwell and recorded in February 2015. Diagnostics at ECMWF is about looking for weaknesses in the forecasting system, trying to identify their causes, working with developers, and documenting the resulting changes in performance. As observation volumes increase, and models get more complex, accurate and represent smaller-scale weather features, and as the need for uncertainty information grows, diagnostic tools need to be ever more powerful and precise. Here, with the help of a few case studies, I will discuss the development of these tools, and how they are helping us identify residual deficiencies.

This webinar was delivered by Mr. Ivan Tsonevsky and recorded in February 2015. The Extreme Forecast Index (EFI) has been developed at ECMWF to alert forecasters to anomalous or extreme weather events by comparing the Ensemble Forecasts (ENS) with the model climate as a reference. The Shift Of Tails (SOT) was implemented in 2012 to complement the EFI by providing additional information about the extremity of a given weather event. This talk will give an overview of the use and interpretation of the EFI and SOT for forecasting extreme weather. It will provide information about some limitations of the EFI products and the future plans in the severe weather forecasting at ECMWF. A lot of practical examples will be used throughout the talk to explain and clarify different aspects of the EFI products in forecasting hazardous and anomalous weather events.

The aim of this webinar is to introduce the main sources of uncertainty that lead to forecast errors. The weather prediction problem will be discussed, and stated it in terms of an appropriate probability density function (PDF). The concept of ensemble prediction based on a finite number of integration will be introduced, and the reason why it is to be the only feasible method to predict the PDF beyond the range of linear growth will be illustrated.This Webinar was delivered by Dr. Roberto Buizza and recorded in May 2014.

Recently, there is in increasing interest in trying to understand the properties of coupled atmosphere, ocean-wave, ocean/sea-ice models with an ultimate goal to start predicting weather, waves and ocean circulation on time scales ranging from the medium-range to seasonal timescale. Such a coupled system not only requires the development of an efficient coupled forecasting system but also the development of a data assimilation component.This lecture was delivered by Dr. Peter Jansen and recorded in May 2014.
