Intraseasonal oscillation (ISO) is the dominant variability during Indian summer monsoon (ISM). In this study, it found that ISOs accompanying intraseasonal rainfall are substantially enhanced over northeastern Arabian Sea (AS) in past three decades. The rise agrees with variation moisture loading. strengthening of wind convergence planetary boundary layer (PBL) triggers changes vertical veloci...
یکی از مواهب الهی برای مناطق مرکزی ایران - در این تحقیق شامل استان های سمنان، اصفهان، یزد و کرمان - بارش های جوی فراگیر است. نتایج این پژوهش، طی دو مرحله تحلیل آماری و تحلیل همدید بدست آمد. در مرحله نخست، با استفاده از معیارهای جمع مقادیر روزانه بارش، دوام موج بارش و گستره آن در شهرهای برگزیده، موج بارش شاخص طی مرطوب ترین زمستان بین سال های 1997 تا 2007 تعیین شد. در مرحله دوم، داده های نقشه های...
The precipitation system and environment causing the heavy rainfall event in July 2020 over Kyushu Island, Japan are analyzed focusing on a hierarchical structure. moisture budget analysis reveals contribution of free-tropospheric flux convergence moistening atmosphere before event. Further analyses by dividing into moisture-advection wind-convergence terms indicate that controlled moistening. ...
in the present paper, we introduce some new sequence spaces derived by riesz mean and the notions of almost and strongly almost convergence in a real 2-normed space. some topological properties of these spaces are investigated. further, new concepts of statistical convergence which will be called weighted almost statistical convergence, almost statistical convergence and statistical convergence...
This paper reports the Ku band (1318GHz) response of thick film equilateral triangle microstrip patch antenna to moisture laden sunflower (Helianthus Annuus) seeds using overlay technique. From the frequency response the moisture dependent microwave permittivity has been reported. The thick film patch antenna is sensitive even to ~ 4.25% moisture content in the overlay material. The actual mois...
Cumulus parametrization started with simple attempts to represent the subgrid-scale effects of convective clouds. Manabe et al. (1965) proposed adjustment towards a moist adiabatic structure in the presence of conditional instability, and Kuo (1965, 1974) proposed a simple cloud model to redistribute the heating and moistening effects of precipitating clouds in the presence of grid-scale moistu...
6 [1] Using sea surface temperature (SST), precipitation, and atmospheric information, this 7 statistical study revisits the questions of the July–September SST‐Sahel teleconnection 8 variability after removing impact of quasi‐global SSTs over the period 1900–2008. The 9 eastern Mediterranean and the Indian Ocean dominate the relationship, both in terms of 10 intensity and time stability, with ...
this study investigates the atmospheric circulation associated with extreme rainfall events over the coastal west africa. the rainfall data of this study were obtained from the global precipitation climatology centre (gpcc), spanning from 1981 to 2010. the atmospheric datasets were also obtained from the era-interim reanalysis. the study employed the z-index to categorize dry and wet years into...
Soil moisture is critical parameters in climatic and hydrological modeling and vegetation growth. Ground-based point measurement of soil moisture is liable but expensive and impractical for watershed measurement. Remote sensing measurement has provided thriving perspective for spatial and instantaneous measurement of soil moisture. Microwave measurement is effective and successful for surface s...
