Extended Abstract 1- Introduction Nowadays, forecasting and modeling the rainfall-runoff process is essential for planning and managing water resources. Rainfall-Runoff hydrologic models provide simplified characterizations of the real-world system. A wide range of rainfall-runoff models is currently used by researchers and experts. These models are mainly developed and applied for simulation...

efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...

Global warming and climate change due to increasing greenhouse gases (GHGs) concentration caused widespread concerns in the national and international societies. Carbon dioxide and methane as the most important greenhouse gases in the atmosphere account for more than about 80% of global warming due to greenhouse gases emission. In this study, Multivariate linear regression (method: enter and st...

the main limitation of radar interferometry in measuring ground displacements is due to phase propagation delays caused by the troposphere. tropospheric water vapor is a major limitation for high precision interferometric synthetic aperture radar (insar)applications. using global meteorological reanalysis models and merisdata are two methods that can be used for correcting the effects of the tr...

While many studies of the effects of global warming on hurricanes predict an increase in various metrics of Atlantic basin-wide activity, it is less clear that this signal will emerge from background noise in measures of hurricane damage, which depend largely on rare, high-intensity landfalling events and are thus highly volatile compared to basin-wide storm metrics. Using a recently developed ...

The main aim of this survey is to investigate the evolution of the OPEC mode of behavior and link the evolution to some important events in the (global) crude oil market. The dominant conclusion of this survey confirms that the primary purpose of OPEC has been to coordinate and unify the petroleum policies of its member countries, in order to secure their individual and collective interests. OP...

The forecasting of time series of the wind and solar energy is necessary for the prevention from global warming. This paper explains the technique of time series forecast of the wind power energy and solar energy by using ten minutes intervals meteorological data obtained by AMeDAS(Automated Meteorological Data Acquisition System). We discuss an application of a neural network for forecasting t...

In recent decades, a decrease in snowfall attributed to the effects of global warming (among other causes) has become evident. However, it is reasonable to investigate meteorological causes for such decrease, by analyzing changes in synoptic scale patterns. On the Iberian Peninsula, the Castilla y León region in the northwest consists of a central plateau surrounded by mountain ranges. This cre...

Climate has always been changing during the lifetime of the earth, and has appeared in the form of the ice age, hurricanes, severe and sudden temperature changes, precipitation and other climatic elements, and has dramatically influenced the environment, and in some cases has caused severe changes and even destructions. Some of the most important aspects of climate changes can be found in preci...

Objective: An increasing number of studies have reported on shifts in timing and length of the growing season, based on phonological, satellite and climatologically studies. Changes in the timing and length of the growing season (GSL) may not only have far reaching consequences for plant and animal ecosystems, but persistent increases in GSL may lead to long-term increases in carbon storage and...
