Abstract: The cirrus-level ?condensation trails? (contrails) produced by jet aircraft are considered to influence surface climate and its recent changes. To reveal the synoptic atmospheric environments typically associated with ...

Abstract: The grounding of all commercial aircraft within U.S. airspace for the 3-day period following the 11 September 2001 terrorist attacks provides a unique opportunity to study the potential role of jet aircraft contrails in ...

Abstract: The increases in total cloud amount documented for large regions during the latter half of the twentieth century have focused attention on the potential contribution from jet condensation trails (contrails). The environmental ...

Abstract: In Part I of this observational study inquiring into the relative influences of ?top down? synoptic atmospheric conditions and ?bottom up? land surface mesoscale conditions in deep convection for the humid lowlands of the ...

Abstract: In the Midwest U.S. Corn Belt, the 1999 and 2000 summer seasons (15 June?15 September) expressed contrasting spatial patterns and magnitudes of precipitation (1999: dry; 2000: normal to moist). Distinct from the numerical ...

Abstract: ontrail statistical prediction methods are often location specific. To take advantage of the fact that the upper-tropospheric (UT) meteorological conditions that favor ?clear-sky outbreaks? of persisting contrails, or ...

Abstract: The possible contribution of jet aircraft condensation trails (contrails) to recent observed increases in high cloudiness constitutes a potentially important human effect on climate that has received relatively little ...
