Workflow diagram - Weather forecast

This work flow chart sample was redesigned from the picture "Weather Forecast" from the article "Simulation Workflows".

"(1) The weather is predicted for a particular geological area. Hence, the workflow is fed with a model of the geophysical environment of ground, air and water for a requested area.
(2) Over a specified period of time (e.g. 6 hours) several different variables are measured and observed. Ground stations, ships, airplanes, weather balloons, satellites and buoys measure the air pressure, air/ water temperature, wind velocity, air humidity, vertical temperature profiles, cloud velocity, rain fall, and more.
(3) This data needs to be collected from the different sources and stored for later access.
(4) The collected data is analyzed and transformed into a common format (e.g. Fahrenheit to Celsius scale). The normalized values are used to create the current state of the atmosphere.
(5) Then, a numerical weather forecast is made based on mathematical-physical models (e.g. GFS - Global Forecast System, UKMO - United Kingdom MOdel, GME - global model of Deutscher Wetterdienst). The environmental area needs to be discretized beforehand using grid cells. The physical parameters measured in Step 2 are exposed in 3D space as timely function. This leads to a system of partial differential equations reflecting the physical relations that is solved numerically.
(6) The results of the numerical models are complemented with a statistical interpretation (e.g. with MOS - Model-Output-Statistics). That means the forecast result of the numerical models is compared to statistical weather data. Known forecast failures are corrected.
(7) The numerical post-processing is done with DMO (Direct Model Output): the numerical results are interpolated for specific geological locations.
(8) Additionally, a statistical post-processing step removes failures of measuring devices (e.g. using KALMAN filters).
(9) The statistical interpretation and the numerical results are then observed and interpreted by meteorologists based on their subjective experiences.
(10) Finally, the weather forecast is visualized and presented to interested people." [iaas.uni-stuttgart.de/ forschung/ projects/ simtech/ sim-workflows.php]

"The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver." [Global Positioning System. Wikipedia]

This interactive voice response (IVR) diagram sample illustrates the IVR services.
"IVR systems are typically intended to service high call volumes, reduce cost and improve the customer experience. Examples of typical IVR applications are telephone banking, televoting, and credit card services. ...
Voice-Activated Dialing
... (VAD) IVR systems are used to automate routine enquiries to switchboard or PABX (Private Automatic Branch eXchange) operators, and are used in many hospitals and large businesses to reduce the caller waiting time. ...
Entertainment and information.
Some of the largest installed IVR platforms are used for televoting on television game shows, ... which can generate enormous call spikes. Often, the network provider will have to deploy call gapping in the PSTN to prevent network overload. ...
Anonymous access.
IVR systems allow callers to obtain data relatively anonymously. Hospitals and clinics have used IVR systems to allow callers to receive anonymous access to test results. ...
Clinical trials.
IVR systems are used by pharmaceutical companies and contract research organizations to conduct clinical trials and manage the large volumes of data generated. ... Applications include patient randomization and drug supply management. ...
Outbound calling.
IVR systems can be used for outbound calls, as IVR systems are more intelligent than many predictive dialer systems, and can use Call Progress Detection to recognize different line conditions...
Other common IVR services include:
Mobile - Pay-As-You-Go account funding; registration; mobile purchases, such as ring tones and logos;
Banking - balance, payments, transfers, transaction history;
Retail & Entertainment - orders, bookings, credit & debit card payments;
Utilities - meter readings; account look-up, history and balance, payment, consumption history;
Travel — ticket booking, flight information, check-in;
Weather forecasts, water, road and ice conditions" [Interactive voice response. Wikipedia]
