This paper describes and analyzes the central role of human–human communication in a dynamic, high-risk environment. The empirical example is a UN peace-enforcing and peace-keeping operation where uncertainty about the situation in the environment and about the own organization’s capability was intertwined, requiring extensive control activities and, hence,(More)
Observations made during late summer in the central Arctic Ocean, as part of the Arctic Summer Cloud Ocean Study (ASCOS), are used to evaluate cloud and vertical temperature structure in the Met Office Unified Model (MetUM). The observation period can be split into 5 regimes; the first two regimes had a large number of frontal systems, which were associated(More)
The Fronts and Atlantic Storm-Track Experiment (FASTEX) will address the life cycle of cyclones evolving over the North Atlantic Ocean in January and February 1997. The objectives of FASTEX are to improve the forecasts of endof-storm-track cyclogenesis (primarily in the eastern Atlantic but with applicability to the Pacific) in the range 24 to 72 h, to(More)
A military command and control function must reduce complexity and resolve uncertainty when confronted by unexpected events, and be able to apply existing knowledge in new situations. Organizational memory research is therefore one of the relevant command and control research approaches. We present observations from a staff exercise, which illuminate some(More)
Defining the averaging time required for measuring meaningful turbulence statistics is a central problem in boundary-layer meteorology. Path-averaging scintillation instruments are presumed to confer some time-averaging benefits when the objective is to measure surface fluxes, but that hypothesis has not been tested definitively. This study uses(More)

The theme of the symposium is “Working together”, the framework being coalition command. Some of its topics are interoperability, harmonizing technology differences, and the management of multicultural complexities. This paper will discuss the work that is conducted during command and control, command work, and what “together” implies and presupposes,(More)
During research about organisational memory(OM), it is discussed whether an organisation can remember at all. The answers vary. Here, the systems theory is used as a way to analyse the concept of memory and describe its functionality. The answer is YES, an organisation has a memory, but it is a memory function, which in itself can be seen as a highly(More)
