Planes' vapour trails affect weather Quote:
The vapour trails left in the atmosphere by jet aircraft have a significant impact on the weather, according to new research.
Scientists in the United States used the grounding of planes following last year's terrorist attacks to show how temperatures changed when flights were at a standstill.
The strips of cloud left by jets in the sky have long been thought to influence the temperature.
But until now, this has been impossible to measure.
The grounding of flights for three days after the 11 September attacks gave scientists in the US a unique opportunity to see what the weather would be like without these vapour trails.
