Global climate models do not have sufficient spatial resolution to represent the atmospheric and land surface processes that determine the unique regional heterogeneity of the climate of the State of Washington. If future large-scale weather patterns interact differently with the local terrain and coastlines than current weather patterns, local changes in temperature and precipitation could be ...

LEAD is a large-scale effort to build a service-oriented infrastructure that allows atmospheric science researchers to dynamically and adaptively respond to weather patterns to produce better-than-real time predictions of tornadoes and other ”mesoscale” weather events. In this paper we discuss an architectural framework that is forming our thinking about adaptability and give early solutions in...

Abstract Past studies have demonstrated that synoptically active weather systems play an important role in the spatial and temporal variations of atmospheric carbon dioxide (CO 2 ) within above planetary boundary layer. For first time, we investigate variability column‐averaged dry‐air mole fractions ( due to impact synoptic scale transport using retrievals from Orbiting Carbon Observatory‐2 (O...

introduction air pollution as one of the most important technological risks of contemporary era is mainly resulted from the emergence of large cities and fast growing industries. one of the main objectives of climatic and environmental studies is to survey atmospheric pollutions. tabriz is one of the metropolises where air pollution is a problem in it. of course, what is essential regarding the...

the aim of this research is the assessment of the relation between rainfall and large scale synoptically patterns at khorasan razavi province. in this study, using adaptive neuro fuzzy inference system, the rainfall estimation has been done from april to june in the area under study. spring rainfall data including the information of 38 synoptic, climatologic and rain gauge stations from 1970 to...

Atmospheric flows are characterized by chaotic dynamics and recurring large-scale patterns. These two characteristics point to the existence of an atmospheric attractor defined by Lorenz as: "the collection of all states that the system can assume or approach again and again, as opposed to those that it will ultimately avoid". The average dimension D of the attractor corresponds to the number o...

Theoretical work and general circulation model (GCM) experiments suggest that themidlatitude jet stream’s interaction with large-scale topography can drive intraseasonal oscillations in large-scale atmospheric circulation patterns. In support of this theory, we present new observational evidence that mountain-induced torques play a key role in 15–30-day oscillations of the Northern Hemisphere c...
