Considering the potential impacts of climate change on meteorological data is likely to be more reliable in design hydrological systems. One recognized methods for assessment influence changes by analyzing weather data. The study aims were inspecting maximum, minimum temperature and rainfall any discernible trends city Delhi between 1901 – 2010 periods. Mann-Kendall non-parametric test includin...

Abstract In this study, to evaluate the trend of precipitation change, Mann–Kendall method has been used. The studied area is Lorestan province located in western part Iran. To achieve goal, time series annual and monthly rainfall data were collected for different statistical periods. Moreover, order analyze drought, standard index non-parametric test predict meteorological drought province, pa...

Climate change is universally occurring but probable fluctuations are not anticipated to be uniform worldwide; rather, there may local differences. Thus, a need investigate the variations at and watershed levels comprehend magnitude of change. This study was conducted determine trend rainfall assess its dependability. In this study, mean monthly annual analysed variability in over period 1984-2...

Gaussian graphical lasso is a tool for estimating sparse graphs using a Gaussian log-likelihood with an 1 penalty on the inverse covariance matrix. This paper proposes a generalization to meta-elliptical distributions. Conditional uncorrelatedness is characterized in meta-elliptical families. The proposed metaelliptical and re-weighted Kendall graphical lassos are computed from pseudo-observati...

Although Ethiopia is endowed with diverse agro-ecologies suitable for cereal production, the success of production relies more on climate condition. Therefore, this study initiated to analyze trends of; crops area and productivity in Ethiopia. Data meher season (qt/ha) (ha) were collected from Central statistical Agency (CSA) Trend test was carried out using non-parametric Mann-Kendall’s ...

It is well established that hepatic abnormalities may occur in patients with rheumatoid arthritis (RA) and other connective tissue disorders and these changes have usually been attributed to the systemic nature of the underlying disease process. Abnormalities reported include minor derangements of liver function (Movitt and Davis, 1953) and other abnormalities which have been related to the sev...

Abstract. Monitoring drought and mastering the laws of propagation are basis for regional prevention resistance. Multivariate indicators considering meteorological, agricultural hydrological information may fully describe conditions. However, series variables in cold arid regions that too short or missing make it difficult to monitor drought. This paper proposed a method combining Soil Water As...

The methods reviewed here are primarily those that are used in atmospheric and oce-anic (physical and biological) studies. These methods are divided into four groups, depending on the type of shifts they are designed to detect, and placed in Tables 1-4. The tables are self-explanatory and provide a brief description of each method, along with the basic references , as well as their strong and w...
