Identify and interpret fields and derived products
Presentation divided into three parts; general description of LSA SAF; applications of LSA SAF products ; and the way foward, i.e. perspectives of LSA SAF.
This session is a wrap up of all applications of the LSA SAF products, feedback from users (annual revision by technical and scientific review panels), lessons learned and roadmap for the next phase (2012-2017).
The presentation is divided into three parts; general description of LSA SAF; applications of LSA SAF products ; and the way forward, i.e. perspectives of LSA SAF.
Presentation during the event week on Warning in October 2010.
Presentation by Tanja Renko (DHMZ) who describes the warning system that was active in Croatia before joining the Meteoalarm. Then the decision process in giving a warning for Meteoalarm and the local authorities will be described using an example of a real warning case.

Presentation by Michael Staudinger talks about the EMMA project and the meteoalarm website that integrates all important severe weather information originating from the official National Public Weather Services across a large number of European countries. The warning information is presented consistently to ensure coherent interpretation as widely as possible throughout Europe.

Rob Groenland will look into more detail in the July 14th case of 2010. He will describe the meteorological part on the synoptic- and mesoscale. Furthermore he pays attention to the decision making process that finally lead to the issuing of a regional weather alarm for parts of the Netherlands that evening. Not only beforehand it is important the follow the procedures carefully but also in the aftermath it is essential to collect all the feedback and communication that took place between the expert- and weatheralarmteam but also from customers, end users and general public. Finally he shows you the results of an extensive KNMI damage survey that took place in the area of the most severe damage.

KNMI takes great interest in collaborative decision making within the process towards issuing severe weather warnings. Collaborative decision making will equalize individual peak reactions by forecasters, it will also decrease the stress often felt by shift meteorologists in the onset phase towards a severe weather event. For this reason KNMI has implemented several consulting procedures within its new warning system.
During the first part of this presentation Frank Kroonenberg will tell you about setting objective warning threshold, the warning colour assignment system and will give more details on the decision making process that leads to a warning for extreme weather or even a weather alarm the highest state of warnings in the Netherlands.

Finnish warnings are issued on 24/7 routines via radio, television and www. Warnings are provided for general public, authorities and commercial clients. Warnings are issued for the next 24 hours in advance, but in future outlooks for some days in advance will be issued in near future. In weather situations where it is estimated that weather will be hazardous an extra forecaster monitors the situation and makes situation awareness reports for authorities. Also authority bulletins for general public are possible in severe weather situations.

Rainfall warnings have not been issued in Finland until 2009. In the earlier years heavy rain forecasting was considered to be a too challenging task. However, growing demand for warnings together with some advancements in forecasts have changed this. Nowadays FMI provides warnings for the general public, authorities and commercial clients. In this presentation FMI's heavy rain warnings are presented and discussed.

Instead of fixed warning thresholds, ZAMG has introduced the principle of annualities for their warning parameters. This decision was also chosen because most European NMSs also do it like this way. A yellow warning means that a situation exists only 17 times per year, which is an event which should be cautiously observed, but for which experience exists; an orange warning describes a situation which is only 3 times per year observed, therefore increased alert is necessary; a red warnng is an event which appears only 1 to 3 times per years and is therefore an extreme event.

Presentation developed by Guido Wolz, Rolf Ullrich, Bernhard Reichert and Wilfried Jacobs on the warning system at Deutscher Wetterdienst (DWD). The issue of weather warnings by DWD is a task according to law. Especially if weather situations can cause danger for persons and material.
The warning management is split in 3 parts: Early warning in which information as possibility (very likely, likely possible) of significant weather situations on a national scale (250-700 km) from 2 day to one week. Pre-warnings in which severe weather situations on a regional scale (50-250 km) from 1 to 2 days is expected. Finally, rural district warnings where concrete warnings are issued for one or more rural district with a preliminary lead time; if necessary with differentiation of height levels.
Presentation during the event week on Fog and Low Clouds in January 2009.
Herve Le Gleau (Meteo-France) will talk about the SAFNWC/MSG cloud type/height parameters. The algorithms, validation results, limitations and recent improvements (to be available to users in March 2009) will be presented and illustrated with low cloud/fog situations. An automatic use at Meteo-France of the NWCSAF/MSG cloud type for fog risk mapping will also be shown.
Presentation during the event week on Convection in June 2009.
In 2008 the Slovakian Meteorological Institute (SHMU) has successfully implemented GII in their forecasting room. The difference being that the ALADIN model is used which provides a higher resolution being helpful to the forecasters. Jan Kanak will present this concept and show some examples.
This talk will be followed by Teodoro La Rocca from Italy on the use of air masses classification in the identification of synoptic conditions favourable to the development of convective phenomena.
Presentation during the event week on Convection in June 2009.
Christo Georgiev from the Bulgarian Meteorological Service will talk about Deep moisture convection (DMC) with the thermodynamic context as seen in WV channels 6.2 and 7.3 of Meteosat Second Generation.
The talk will be followed by a practical session done by Estelle deConing from the South African Weather Service who will talk about the successful implementation of GII (Global Instability Index) and the operational use of it, at their weather service using their model as first guess.
