Previous studies have demonstrated the key role of baroclinicity and thus the isentropic slope in determining the climatological-mean distribution of the tropospheric eddy fluxes of heat. Here the authors examine the role of variability in the isentropic slope in driving variations in the tropospheric eddy fluxes of heat about their long-term mean during Northern Hemisphere winter. On month-to-...

abstract drought is a natural creeping event that starts due to lower moisture compared to normal condition. this phenomenon impacts all aspects of human activities. however there is neither any detailed definition nor a general and proper index for drought monitoring. in this study, fuzzy logic has been applied to deal with inherent uncertainties of the real world data. we presented a fuzzy mo...

An adaptation technique based on the synoptic atmospheric circulation to forecast local precipitation, namely the analogue method, has been implemented for the western Swiss Alps. During the calibration procedure, relevance maps were established for the geopotential height data. These maps highlight the locations were the synoptic circulation was found of interest for the precipitation forecast...

Gangguan pada sistem tenaga listrik bisa menimbulkan bahaya bukan hanya untuk peralatan tetapi juga manusia yang bekerja didekatnya. dapat muncul mulai dari konslet menyebabkan percikan api, hingga hubung singkat busur api. Tingkat api diperkirakan menentukan Personal Protective Equipment (PPE) harus digunakan oleh jika di daerah beraliran listrik. Selain level PPE, nilai arus jarak aman antara...

Dalam ini akan memanfaatkan terbarukan yaitu matahari pengendalian kecepatan motor induksi tiga fasa. Energi dihasilkan dari panel disimpan pada baterai untuk menjadi inverter Tujuan a...

The loess hilly-gully region is a focus region of the "Grain for Green" program in China. Drought is the main problem in the study region. Precipitation and temperature are two indicators that directly characterize climatic drought. A thorough analysis of the precipitation, temperature and drought characteristics of the loess hilly-gully region can clarify the current water and heat conditions ...

Background: Toxoplasmosis is a parasitic disease caused by protozoan, Toxoplasma gondii. Infections of human are common and are usually asymptomatic. The infection may be serious if is transmitted to the fetus during pregnancy. Prophylactic measures, early detection of the infection and treatment can avoid congenital toxoplasmosis and many long term effects. Objective: Seroepidemiological study...
