“…Among them the SPI and the SPEI has been widely used all over the world (e.g. Italy (Caloiero and Veltri 2019); India (Kumar et al 2019); Portugal (Raziei et al 2015); Syria (Mathbout et al 2018); Syria (Mohammed et al 2019); Slovakia (Labudová et al 2017;Vido et al 2019); Kenya (Ayugi et al 2020); Serbia (Bezdan et al 2019); the USA (Hernandez and Uddameri 2014) and China (Wang et al 2016;Fang et al 2018;Jin et al 2019) for analyzing different types of drought, including meteorological, agricultural, hydrological and socioeconomic drought.…”

Historically, Hungary has witnessed numerous waves of drought episodes, causing significant agro-economic loss. Over the recent decades, the intensity, severity and frequency of drought occurrence have dramatically shifted, with undisputable upward tendencies across many areas. Thus, the main aim of this study was to characterize drought trends, intensity and duration over Hungary during 1961-2010. To attain the study goals, the present analyses utilized climate datasets obtained from Climate of the Carpathian region project-CARPATCLIM for 1045 gridded points covering entire Hungary. Meanwhile, a well-known drought index, namely; standardized precipitation index (SPI) and the standardized precipitation evapotranspiration index (SPEI) at 12-month timescales were employed for drought characterization. Furthermore, the sub-set regions of drought in Hungary were identified using S-mode of the principal component analysis. The Mann-Kendall trend test analysis showed a significant negative SPI-12 trend (P \ 0.05) in 11.5% of the total points over the western part of Hungary. In comparison, 43.2% of the total numbers of the SPEI-12 time series gridded points showed a significant negative trend (P \ 0.05) over the similar locale. However, both indices' trends highlighted the fact that the northeastern region is less sensitive to drought despite experiencing the highest of total drought duration. Results also suggested that the SPI-12 indicates that no significant change can be detected from 1961 to 2010 over Hungary. In contrast, the SPEI-12 exhibits that the drought waves that hit Hungary were more pronounced, with a significant positive (P \ 0.05) trend of ? 1.4% per decade being detected for the area affected by very extreme drought. All in all, this study is one of the primary steps toward a better understanding of drought vulnerability assessment in Hungary.

“…The temperature and pressures after leaving the IMS drive end is connected to the HSS drive end where the rate of the power is to be increased with respect to initial velocities and the temperatures that attained during this time period was attained up to a maximum of 110 ο C. This is due to the less viscous in nature given by de Azevedo et al [24]. Hence the temperature distribution for the HSS drive end and HSS non drive end projects the overall performance of the turbine with respective Active power, however in case of failure in sensors results the heavy breakdown maintanence in the period of fall in wind velocities given by Kumar et al [25].…”

This research work is mainly focused on the performance of the wind turbine power plant. The performance of the plant will depends on the working of wind turbine gearbox. Hence the parameters taken like inlet velocity of air, inlet temperatures and inlet pressure of the air entering into the gearbox. For experimentation a three stage gearbox has been considered and the data has been recorded for the period of 5 months. These results has been recorded with the help of SCADA software and the results are imported from SCADA for analyzing the minimum and maximum oil temperatures. Since these parameters effects directly on the thermal performance of the wind turbine power plant. From the analysis it was found that the temperature sensors for monitoring the oil TM1 and TM2 within temperature limits of 250οC and also the TS1 and TS2 Promises the sensing capacity within temperature limits up to 200 οC and response time is 30 minutes, also the coupling temperatures TC1 and TC2 gives very promising results upto 150 οC for 30 minutes response time.

“…Mean precipitation: The most prominent features about changes in precipitation over Asia are the increasing precipitation trends across higher latitudes, along with some scattered smaller regions of detectable increases and decreases (Knutson and Zeng, 2018); however, spatial variability remains high (W.
