in this study, a new array of meteorological elements and a synoptic climatologic classification to produce abaseline climate and to derive meteorological factors that are effective on air pollution in tehran, which is located in a semi-enclosed basin was developed. the data set includes daily sea-level pressure and 500mb geopotential height fields from ncep-ncar and tehran upper air sounding d...

Abstract. In this study, the first fully continuous monitoring of water vapour isotopic composition at Neumayer Station III, Antarctica, during 2-year period from February 2017 to January 2019 is presented. Seasonal and synoptic-scale variations in both stable isotopes H218O HDO are reported, their links key meteorological variables analysed. addition, diurnal cycle isotope summer months (Decem...

As part of a larger analysis of country systems described elsewhere, named a Crop Country Inventory, CCI, large variations in annual crop yield for selected climate sensitive agricultural regions or sub-regions within a country have been studied over extended periods in decades. These climate sensitive regions, principally responsible for large annual variations in an entire country’s crop prod...

29 The influence of synoptic-scale circulations on air quality is an area of increasing interest to 30 air quality management in regards to future climate change. This study presents an analysis 31 where the dominant synoptic " types " over the region of Melbourne, Australia are determined 32 and linked to regional air quality. First, a self-organising map (SOM) is used to generate a 33 time se...
