“…Moreover, depending on the site, significant shifts in P between months agree in terms of direction, but vary in size ( Table 3), indicating that local factors play a role in the resulting change [22]. Hence, it seems not surprising that significant linear trends in annual and seasonal area precipitation for the Carpathian region are (currently) absent, as shown in [6].…”

“…However, on the basis of regional climate simulations at a spatial resolution of 25 km, projected 21st century changes (2070-2099 versus 1970-1999) in Alpine precipitation include a decrease in the frequency of wet days in the summer accompanied by an increase in mean precipitation in the winter [5]. Concerning the Carpathian region, with its highest range (Tatra Mountains), the identified significant trend in annual mean surface temperature representing the entire area was found to be increasing, with a rate of change of 0.27 • C per decade ; and for the period since 1981, a higher warming rate of 0.51 per decade has been identified [6]. Wind speed was found to decrease in every season, while relative sunshine duration increased.…”

“…Subsequently, owing to a stronger warming trend in surface temperature in the Carpathian region since the 1980s [6] and the available data, comparative analyses were conducted for data from the years 1986-2015 versus 1956-1985. Therefore, each precipitation time series was divided in half, covering two 30-year periods (1956-1985 and 1986-2015), and then arranged as the matrix P ij , where the index i (for row) represents a year, and the index j (for column) represents a month.…”

This study analyzes changes in long-term patterns of precipitation and river flow, as well as changes in their variability over the most recent 60 years . The study area is situated in the mountain basin of the Dunajec River, encompassing streams draining the Tatra Mountains in southern Poland. The focus of the study was to evaluate how regional warming translates into precipitation changes in the studied mountain region, and how changes in climate affect sub-regional hydrology. Monthly time series of precipitation measured at several sites were compared for two 30-year periods (1986-2015 versus 1956-1985). The significance of the difference between the periods in question was evaluated by means of the Wilcoxon signed rank test with the Bonferroni correction. The identified shifts in precipitation for 6 months are statistically significant and largely consistent with the revealed changes in river flow patterns. Moreover, significant differences in precipitation variability were noted in the study area, resulting in a significant decrease in the repeatability of precipitation over the most recent 30 years . Changes in the variability of the river flow studied were less visible in this particular mountain region (while significant for two months); however, the overall repeatability of river flow decreased significantly at the same rate as for precipitation.

“…In this way, statistical correction models can be equipped with more spatial information compared to those using merely local meteorological factors. While weather classification has been widely used in many fields, such as climate analysis [24][25][26], wind reconstruction [27] and weather prediction [28,29], it has not been conventionally applied or considered in the wind energy field for the forecast bias correction.…”

Abstract:Wind forecasting is critical in the wind power industry, yet forecasting errors often exist. In order to effectively correct the forecasting error, this study develops a weather adapted bias correction scheme on the basis of an average bias-correction method, which considers the deviation of estimated biases associated with the difference in weather type within each unit of the statistical sample. This method is tested by an ensemble forecasting system based on the Weather Research and Forecasting (WRF) model. This system provides high resolution wind speed deterministic forecasts using 40 members generated by initial perturbations and multi-physical schemes. The forecasting system outputs 28-52 h predictions with a temporal resolution of 15 min, and is evaluated against collocated anemometer towers observations at six wind fields located on the east coast of China. Results show that the information contained in weather types produces an improvement in the forecast bias correction.

Centre pivot machines, with a variable rate irrigation (VRI) package that provides individual sprinkler control systems (VRI iS), are not common. This research focuses on how uniform the water distribution is under VRI control, and on the size of over‐ and under‐irrigated areas and volumes. Moreover, we wanted to know how wide transition zones are. We conducted different uniformity measurements using common rain gauges for measuring water application depths. Besides grid shape and radial direction measurements for uniformity, perpendicular measuring lines to borders were set to evaluate transition zones. In a processing tomato deficit irrigation experiment, we investigated how different plant properties react to different water depths. Results showed that very good uniformity is achievable both in the IR100 and IR50 application rates, but the former showed higher uniformity. CUC ranged from 91.8 to 92.9% and 88.8 to 90.8% in the IR100 and IR50 rates respectively. The highest RMSE was 2.65 mm. The amount of over‐ and under‐irrigation was not significant. Transition zones were not equally wide; 9 m was enough for transition widthways between the IR100 and IR50 rates, but was wider longitudinally. This technology is suitable for conducting deficit irrigation experiments, but consideration of transition zones is important at plant sampling. © 2018 John Wiley & Sons, Ltd.
