Transatlantic flight times and climate change
Aircraft do not fly through a vacuum, but through an atmosphere whosemeteorological characteristics are changing because of global warming. The impacts of aviation on climate change have long been recognised, but the impacts of climate change on aviation have only recently begun to emerge. These impacts include intensified turbulence and increased take-off weight restrictions. Here we investiga...

متن کاملImpact of the North Atlantic Oscillation on Transatlantic Flight Routes and Clear-Air Turbulence
The variation of wind-optimal transatlantic flight routes and their turbulence potential is investigated to understand how upper-level winds and large-scale flow patterns can affect the efficiency and safety of long-haul flights. In this study, the wind-optimal routes (WORs) that minimize the total flight time by considering wind variations are modeled for flights between John F. Kennedy Intern...
متن کاملThe Transatlantic on 2200 Meters
here has been much excitement below our so-called top band at 1.8 MHz. At less than one-tenth this frequency, near 136 kHz, you will find many amateurs enjoying QSOs using a variety of modes. Although US and Canadian amateurs need special permission to transmit here, there is a 2200 meter amateur band in many European countries and in New Zealand. Aside from its low frequency, the most striking...
متن کاملTCP Behavior on Transatlantic Lambda's
Recent research in the area of high speed TCP has revealed that the protocol can misbehave in cases of high bandwidth long delay networks. Here we present work that clearly demonstrates this behavior of TCP flows in detail. This examination has led us to study the influence of the underlying network as well as the end user system using bursty a protocol such as TCP under such conditions. We des...
