â â  in this research, temporal and spatial behavior of subtropical high pressure was studied at the level of 600 hpa. this study has been done using daily data of geopotential height at 12 gmt in ncep/ncar database with spatial resolution of 2.5ã—2.5 degree in a 55 years period including 20089 days from january, 1st, 1951(dey, 11th, 1329) to december, 31st,2005(dey, 10th,1384). at first, the m...

UNLABELLED This study had two aims: (a) to describe the quality of language intervention provided by school-based speech-language pathologists (SLPs) to children with language impairment in the primary grades with respect to the quality of emotional support, instructional support, and proactive management during SLP-child interactions, and (b) to determine if key characteristics of the SLPs are...

introduction subtropical high pressure is one of the main elements of the general circulation of the atmosphere. annual motion of the circulation plays an important role in movement path of pressure systems and westerlies. hence, large parts of the planet are affected directly and indirectly by this system. sometimes the high pressure called the subtropical high pressure belt. it’s shown as sev...

The evolution of mean sea-level atmospheric pressure since 1850 is analyzed using iterative singular spectrum analysis. Maps the main components (the trends) reveal striking symmetries order 3 and 4. Northern Hemisphere (NH) displays a set three positive features, forming an almost perfect equilateral triangle. Southern (SH) features arranged as isosceles triangle, with possible fourth (weaker)...

Millions of sub-daily sea-level pressure observations taken between 1919 and 1960 over the British Irish Isles were transcribed from paper records in early 2000s but not published subsequently forgotten. A chance discussion led to rediscovery data 5.47 million 160 locations are now made available, although have been fully quality-controlled. Much 3-hourly, allowing for detailed examinations syn...

Abstract The late-winter signal associated with the El Niño-Southern Oscillation (ENSO) over European continent is unsettled. Two main anomalous patterns of sea-level pressure (SLP) can be identified: a “wave-like” pattern two opposite-signed anomalies Europe, and showing single anomaly (“semi-isolated”). In this work, potential paths tropospheric ENSO teleconnection to Europe their role in fav...

Time-series of growing season air temperature anomalies in the Parisian region and of Pinot noir grape harvest dates (GHD) in Burgundy (1676–2004) are analyzed in the frequency domain. Variability of both time-series display 3 significant frequency-bands (peaks significant at the 5% level): (1) a low-frequency-band (multi-decadal) with a 25 yr peak period, (2) a 3 to 8 yr band period (inter-ann...
