[1] The statistical relationship between the daily 1-hour maximum ozone (O3) concentrations and the daily maximum upper air temperature was explored for California’s two most heavily polluted air basins: the South Coast Air Basin (SoCAB) and the San Joaquin Valley Air Basin (SJVAB). A coarse-scale analysis of the temperature at an elevation of 850-mbar pressure (T850) for the period 1980–2004 w...
During the early summer rainy season over Taiwan, three types of low-level jets are observed, including a synoptic jet (SLLJ) situated in 850–700 hPa layer frontal zone, marine boundary (MBLJ) embedded within southwesterly monsoon flow northern South China Sea at approximately 925 level, and an orographically induced 1 km level off northwestern Taiwan coast (e.g., barrier (BJ)). The characteris...
mazafati date is a wet and semi-dried date fruit type with dark red to black color that has premier quality. because of its high moisture content, date fruits of this variety are very perishable at room temperature and therefore must be refrigerated during storage. in this study, effect of air temperature (50, 60, 70, 80 and 90 ˚c) and air flow rate (1, 1.5 and 2 m/s) in hot air drying of mazaf...
A simple model using once-daily US National Centers for Environmental Prediction/US National Center for Atmospheric Research (NCEP/NCAR) re-analysis upper-air values estimates winter balance, summer balance and net balance at ten glaciers in Norway and two in Sweden with 0:37 r2 0:90: The October–May Arctic Oscillation (AO), an index of sea-level pressure (SLP) in the Northern Hemisphere, corre...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
کشور ایران به جهت قرار گیری بر روی کمربند بیابانی نیمکره شمالی، آب و هوای خشک و بیابانی بر قسمت های زیادی از آن مستولی است. به دلیل همین موقعیت جغرافیایی ریزش های جوی در حیات و زندگی انسانی و جانوری آن نقش بسیار مهمی دارد و با توجه به این که منابع رطوبتی کشور در خارج از آن قرار دارد و این ریزش های جوی از سالی به سال دیگر نوسان دارند نقش سامانه های باران زا پررنگ تر می شود. یکی از مکانیسم های مه...
Radiosonde data have been used, and will likely continue to be used, for the detection of temporal trends in tropospheric and lower-stratospheric temperature. However, the data are primarily operational observations, and it is not clear that they are of sufficient quality for precise monitoring of climate change. This paper explores the sensitivity of upper-air temperature trend estimates to se...
The Tropical Rainfall Measuring Mission (TRMM) and ERA5 reanalysis data are used to research the asymmetric precipitation induced by tropical cyclone (TC) Nada, which made landfall on southeastern coast of Indian Peninsula December 2, 2016. mechanism is analyzed during passage TC. results show that spatial average rate increased a maximum 1.78 mm/hr Peninsula, where vorticity TC center more tha...
We present analyses of a lacustrine sediment core (DY6) on Dongdao Island, which provides high-resolution paleoclimate records for the South China Sea (SCS). Results of element analyses indicate that the concentrations of Ti and Al in DY6 are much higher than the background on the island. Morphological characteristics of acidic insoluble particles are similar to aeolian in East China. Sr and Nd...
