Identify and interpret atmospheric phenomena
The presenter gives an overview into the mechanisms of convective lines connected to winter storms such as Emma.
Convective lines in connection with intense cyclogenesis hit Middle and Western Europe almost every winter season. These lines move very quickly and are often connected with thunderstorms, heavy gusts and graupel or even hail. In this presentation the related conceptual model and the preconvective environment will be explained. Based upon different satellite products and additional data two examples will be discussed.
The presenter is senior forecaster at the Norwegian Met-Institute in Tromso. He refers on the synoptic aspects of Polar Lows.
The forecasting of Polar Lows is one of the most challenging tasks in weather forecasting in the arctic. The lecture will give a demonstration of basic forecasting methodology at the Norwegian Meteorological Institute, and show some typical signatures of the polar low as seen from satellite IR/visible imagery, from ASCAT and from other observational data. A climatologic survey is also given by the presenter.
The invention of weather satellites has opened a new area in weather forecasting. This presentation will give you an introduction from the early starts to the future with the third generation of satellites.
The invention of weather satellites has opened a new area in weather forecasting. Satellite observations enable to continuously monitor the weather regimes on the whole globe. Therefore they provide a powerful tool in weather forecasting. The first lecture of the satellite course leads from the invention of weather satellites to technical inventions and the current operational satellites.
Presentation on some of the typical convective scenarios with the focus on the usage of the background NWP fields and convective parameters in combination with satellite imagery.
Zoltan Polyanszky from the Hungarian Meteorological Institute, presents some of the typical convective scenarios with the focus on the usage of the background NWP fields and convective parameters. The role of the operational work of the forecaster who is responsible for issuing warnings is highlighted and concluding a reflection is discussed on what has been learned from the situations over the recent years.
Presentation during the event week on Convection in June 2011 by Helge Tuschy on the European Forecasting Experiment (ESTOFEX).
Presentation by Helge Tuschy from Deutscher Wetterdienst (DWD). He is one of the forecasters producing the valuable ESTOFEX forecasts and this lecture is on the basics of convection and how the convective outlooks in ESTOFEX are prepared.
Webcast on the influence of the the Black Sea on the initiation of convective storms in South Eastern Romania.
Presentation by Aurora Bell on the influence of the the Black Sea on the initiation of convective storms in South Eastern Romania. Several cases with Doppler radar and satellite images were presented in combination with other integrated data. The presentation was oriented towards forecasters and Aurora explained the role of the sea breeze in bringing together the right ingredients.
Presentation on the use of the MPEF Divergence Product for diagnosing the divergence associated with upper-level wind field disturbances that produces forcing for ascent and favours the development of deep moist convection.
Presentation by Christo Georgiev during the Event Week on Convection in June 2011. The presentation concentrates on the use of the MPEF Divergence Product for diagnosing the divergence associated with upper-level wind field disturbances that produces forcing for ascent and favours the development of deep moist convection.
Webcast on the detection and monitoring of convective storms by using MSG imagea and products.
Aydin Erturk (TSMS) present on the "Detection and Monitoring Convective Storms by Using MSG Image and Products". The MSG SEVIRI is crucial data source for the nowcasting applications. Storm top features with IR imagery were well defined and published. MSGView software being operationally used for detection and monitoring convective storms at Turkish State Meteorological Service. Two case studies (a cold U/V and a cold ring shape) were demonstrated and discussed in this presentation.
Webcast on the use of IR8.7 for the detection of deep moisture convection.
Presentation given by Thomas Krennert (ZAMG) on the use of the IR8.7 channel for the detection of deep moisture convection (DMC) on marked WV boundaries.
The EUMETCAL High Impact Weather group addressed a series of convective events over Europe during the summer 2010.
The EUMETCAL High Impact Weather group addressed a series of convective events over Europe between 5 and 9 August 2010. This events affected many countries from southern areas - Mediterranean/Balkans - to northern areas - Baltic/Scandinavia. In the 30 minute presentation the group analyzed the events, combining the analysis of convection, namely by satellite, with the impacts perspective.
Presentation with results on the occurences of overshooting tops in convective clouds in relation to severe weather.
Presentation given during the Convection Week 2011 by Petra Mikus, a young researcher from the Croatian Meteorological and Hydrological Service DHMZ. The presentation presents results on the occurrences of overshooting tops in convective clouds in relation to severe weather in Austria, Slovenia and Croatia.
For knowing which processes are present in the atmosphere good interpretation of WV satellite images is needed. For gathering information about water vapor, SEVIRI instrument on board MSG satellite is scanning atmosphere in two channels in water vapor absorption band; 6.2 and 7.3 µm.
WV images are like a footprint of absorption of radiation by a water vapor, which is the main absorber in the atmosphere. Therefore it is clear that understanding of these images can tell us a lot about footprint of atmosphere itself and about processes in it. For knowing which processes are present in the atmosphere good interpretation of WV satellite images is needed.
For gathering information about water vapor, SEVIRI instrument on board MSG satellite is scanning atmosphere in two channels in water vapor absorption band; 6.2 and 7.3 µm. Among these two WV channels, the radiation in channel 6.2 µm is more easily absorbed by water vapor and has a larger information content. Thus is called primary WV channel and is broadly used in image format for weather analysis and forecasting based on synoptic scale interpretation. 7.3 µm channel can also be used in operational forecasting environment for detecting mid-level moisture features associated with low-level thermodynamic conditions. Presenter for this one hour lesson is Christo Georgiev, from Bulgarian National Institute of Meteorology and Hydrology.
