Aviation Diplomacy und (un-)erwünschte Mobilität am Frankfurter Flughafen, 1945–1990er Jahre

Österreichische Zeitschrift für Geschichtswissenschaften
Today, almost every state visit begins at the airport. Yet air routes not only make diplomatic travel possible, they are also themselves at the center of diplomatic initiatives.

Productivity Growth and Biased Technological Change in UK Airports [PDF]

In this paper we estimate the total factor productivity of UK airports using a Malmquist index. Productivity change is factored into an index of efficiency change and an index of technological change.

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

The Impacts of Airport Centrality in the EU Network and Inter- Airport Competition on Airport Efficiency [PDF]

In this paper we study the relationship between airport efficiency and two factors: an airport’s centrality in the EU network, and the intensity of competition from alternative airports in the same catchment area.

An opportunity index to anticipate when subseasonal predictions are useful

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Simultaneously active subseasonal windows of forecast opportunity can be combined into a single opportunity index, which can be used operationally to anticipate enhanced or reduced subseasonal prediction skill. For predictions of temperature anomalies in Switzerland during summer—a region and season with particularly low predictability—skill can nearly

Modulation of wind drag by tidal currents in an embayment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

An Assessment on the Cost Structure of the UK Airport Industry: Ownership Outcomes and Long Run Cost Economies [PDF]

In this paper we analyze the cost structure of the UK airport industry by estimating a variable cost function for the period 1994-2005. Overall results suggest that the long run average costs curve is U-shaped: it decreases until passenger traffic ...

Evidence of Passenger Preferences for Specific types of Airports

, 2010
Studies of air travel choice behaviour increasingly make use of data collected through stated choice surveys. Here, we put forward the hypothesis that when making their choices in such surveys, respondents may complement the information presented to them
