Item Delivery and communication of severe weather events in Basque Country: the Euskalmet case(Copernicus Publications, 2016-06-10) Gaztelumendi, Santiago; Orbe, Iñaki; Salazar, Onintze; López, Ana; Aranda, Jose Antonio; Anitua, P.In this work we briefly introduce some aspects about delivery and communication of severe weather events in Basque Country, explaining what is considered severe weather by the Basque Meteorology Agency (Euskalmet) in the context of Basque Country. We include a short description of some products generated for different purposes during such events, presenting different aspects related with delivery and communication processes in the operational context of Euskalmet. We review some real examples on severe weather communication and message dissemination in Basque Country. Finally, some conclusions about our experience are presented.Item The new Euskalmet coastal–maritime warning system(Copernicus Publications, 2016-06-10) Gaztelumendi, Santiago; Egaña, J.; Liria, Pedro; González, Manuel; Aranda, Jose Antonio; Anitua, P.This work presents the main characteristics of the Basque Meteorology Agency (Euskalmet) maritime–coastal risk warning system, with special emphasis on the latest updates, including a clear differentiation on specific warning messages addressing sea conditions for navigation purposes in the first 2 nautical miles, and expected coastal impacts. Some details of the warning bulletin for maritime and coastal risk situations are also presented, together with other communication products and strategies used in coastal and maritime severe episodes at the Basque coast. Today, three different aspects are included in the coastal–maritime risk warning system in Basque Country, related to the main potential severe events that affecting coastal activities. – "Galerna" risk relates to a sudden wind reversal that can severely affect coastal navigation and recreational activities. – "Navigation" risk relates to severe sea state conditions for 0–2 miles, affecting different navigation activities. – "Coastal impact" risk relates to adverse wave characteristics and tidal surges that induce flooding events and different impacts in littoral areas.Item An overview of a regional meteorology warning system(2012-08-09) Gaztelumendi, Santiago; Egaña, J.; Otxoa de Alda, K.; Hernández, Roberto; Aranda, J.; Anitua, P.In this work we present a regional meteorology warning system, particularly the operational weather warning system used by the Basque Meteorology Agency (Euskalmet) for Basque Country. System considers different meteorological phenomena capable of generate warnings, and is based on combined thresholds criteria depending on particular weather event and area of territory where is applied. In this work we describe the most significant aspects related with the warning event definition and the warning bulletin. Conclusions from comparison with the former system (prior to 2009) and feedback from different users are presented.Item An overview of the use of Twitter in National Weather Services(Copernicus Publications, 2015-06-30) Gaztelumendi, Santiago; Martija, M.; Príncipe, Olatz; Palacio, VirginiaTwitter is a service that enables users to post messages ("tweets") of up to 140 characters supporting a variety of communicative practices. In this paper we analyze different aspects related to the use of Twitter in different National Meteorological Services (NMS) worldwide. Firstly, we will review the general position of NMS worldwide regarding the use of Twitter technology. Secondly, we will focus on different practices of some selected meteorological services. Thirdly, we will deal specifically with the Basque Meteorology Agency (Euskalmet) case. Finally some conclusions are presented.Item Quality control procedures at Euskalmet data center(Copernicus Publications, 2012-06-15) Hernández, Roberto; Maruri, M.; Otxoa de Alda, K.; Egaña, J.; Gaztelumendi, SantiagoThe Basque Country Mesonet measures more than 130 000 observations daily from its 85 Automatic Weather Stations (AWS). It becomes clear that automated software is an indispensable tool for quality assurance (QA) of this mesoscale surface observing network. This work describes a set of experimental semi-automatic quality control (QC) routines that is applied at Euskalmet data center. It has paid special attention to level validation design and associated flags, as well as to the system outputs, which are used by meteorologist and maintenance staff.
