3 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Warning Management System of Deutscher Wetterdienst
DWD Law calls for "the issuance of official warnings of weather phenomena that could become a danger for public safety and order".
DWD operates a three-tiered warning management system (in time dimension)
it has five risk levels
warning management system is co-ordinated with disaster management of the federal states, which in Germany are responsible for disaster management
Deutscher Wetterdienst (DWD) is a federal authority under the Federal Ministry of Transport, Building and Urban Affairs, established in response to the Law on the Deutscher Wetterdienst (DWD Law).
4 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Warning Management System of Deutscher Wetterdienst
DWD likewise issues warnings
to safeguard marine shipping and the sea coasts
against extreme heat and UV radiation (Dep. Human Biometeorology)
Aviation warnings (Dep. Aeronautical Meteorology)
DWD publishes a forest fire danger index (Dep. Agrometeorology)
Flood forecasting is the responsibility of the federal states where specific flood response centres are operated. Their forecasts rely on the meteorological information and forecasts supplied by DWD.
5 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Warning Management System of Deutscher Wetterdienst
The three levels of warning management system are:
Weekly Weather Hazard Forecast: following 2 to 7 days
probability of occurence of severe weather based on numerical models
Severe Weather Watch: 48 - 6 h
hazardous weather phenomena is very likely; offered for regions
Warning: ~ 12 - 0 h
for different weather phenomena
issued no more than 12 hours before the arrival of the warning event
6 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Warning Management System of Deutscher Wetterdienst
Geographical structures
rural districts (in vertical: 200m steps), ca. 400 districts
great lakes (i.e. lake Constance)
some parts of rural districts (i.e. seasides, mountain areas)
7 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Providing channels for warnings:
dissemination via Internet
fax-on-demand services
text messages (SMS)
in specific cases, also by telephone
ftp server (for download by customers)
general public is informed over the Internet (http://www.dwd.de)
closed online user groups (i.e. FeWIS for fire brigades; SWIS for winter maintenance service)
voluntary support of radio and television companies (There is no obligation on radio stations to disseminate
the DWD's warnings on television and radio because there are no legal regulations applicable to this area.)
Warning Management System of Deutscher Wetterdienst
8 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Closed online user groups
SWIS (Road Weather Information System)
provides support for winter maintenance service management
delivers all warning information in special form for users
provides information about road conditions, forecasts of road conditions
Warning Management System of Deutscher Wetterdienst
9 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Closed online user groups
FeWIS (Weather Information System for Fire Brigades)
targeted at the needs of professional fire services
delivers a warning overview, a warning situation report, severe weather watches and district-related warnings
provides many other types of information (weather radar, satellite loops, supplementary information about temperatures, precipitation, wind peaks, frost penetration depths, snow depths, forecast texts)

16 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
CAP products of DWD
Public warning products as CAP XML documents (format UTF-8, CAP version 1.2)
Typical textbased warnings (format (ia5, txt)) are transformed into CAP version 1.2
Up to 35.000 different products (depending on warning situation)
Warning status of Germany as one CAP document AND Warning status of Germany as one Zip-Container of different CAP documents
published every 5 minutes
Including geographic details of warning areas (e.g. polygons)
an alternative product (including only geo-references) is scheduled
CAP aviation products
Wind shear warning as CAP document

24 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Benefits of CAP documents
CAP – a powerful format of alerts and warnings:
Clear strukture
Minimized „xml-overhead“
Well-established international standard
Useful format not only of alerts and warnings
25 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Validation and profiling
Validation against xml schema (e.g. OASIS (CAP-v1.2.xsd)) Basic validation (independent of alerting scope)
Weak restrictions for the content of most of xml tags
Semanical checks are impossible (unable to check relations between content of different xml tags)
Profiling against own xml schema (https://werdis.dwd.de/conf/CAP-DWD-Profil-v1.9.xsd, documentation: https://werdis.dwd.de/infos/legend_warnings_CAP.pdf) Based on official xml schema (OASIS, CAP-v1.2.xsd)
Stronger restrictions for the content of relevant xml tags (e.g. basic type „string“ <-> enumeration of strings)
Semantical checks are impossible (unable to check relations between content of different xml tags).
Profiling against a combination of official xml schema AND own „schematron roles“ „two step“-validation ( 1. step: validation against OASIS, CAP-v1.2.xsd,
2. step: check against own schematron roles)
Semantical checks are possible.
Schematron – ISO standard since 2006

Open issues (Relation CAP / ISO 19xxx: Measure)
CAP: units unsolved
ISO19xxx:range of values(from .. to ..) andthresholds (>.. or <..)unsolved
27 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Open issues (Proposals)
Workaround (DWD / MeteoAlarm)
Optional attribute:„uom“ (unit of measure, like ISO19XXX)
28 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Open issues (CAP: geographic Objects)
CAP:Information about an area:
Useful area definition
But:
Bounding box(unsupported)
Altitude and ceiling only in feet (not compliant to German /European law)
30 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Open issues (Proposals)
Workaround (DWD /MeteoAlarm):
Conversion into feet
Without optional attribute feet
With optional attribute e.g. meter
Proposal:optional attribute „uom“ (unit of measure, like ISO19XXX)
compliant to current CAP-schema
31 Petra Fechner, Siegfried Fechner – DWDGeneva, April 2013
Design and technical aspects (best practices)
Best practices should be useful
Recommendations for identifiers
Recommendations for meteorological measurements
Recommendations for profiling / validation
