performance of chamomile (matricaria chamomilla l.) was evaluated on twelve transplanting dates that were arranged at 30 days interval; during 2013-2014 on experimental field of wondo genet agricultural research center; using rcbd design with three replications. transplanting time exerted a very highly significant (p<0.0001) influence on plant height, flower yield and essential oil yield; essen...

weather circulation patterns play a main role in the occurrence of environmental phenomena especially in middle latitude. occurrence of dry and wet spells is in relation to synoptical system repetitions and types of weather. in this research first by using of standard precipitation index (spi), extensive droughts in the province were identified. then by using principal component analysis (pca) ...

PV inversion techniques have been widely used in numerical studies of severe weather cases. These techniques can be applied as a way to study the sensitivity of the responsible meteorological system to changes in the initial conditions of the simulations. Dynamical effects of a collection of atmospheric features involved in the evolution of the system can be isolated. However, aspects, such as ...

A fundamental function of any aviation weather system is to provide accurate and timely weather information tailored to the specific air traffic situations for which a system is designed. Weather location and intensity are of prime importance to such systems. Knowledge of the weather provides “nowcasting” functionality in the terminal and en route air spaces. It also is used as input into aviat...

[1] This study investigates how increasing city size affects local weather modification potential using an innovative new method: the real atmosphere, idealized land-surface (RAIL) method. The RAIL method simplifies the land surface by making a flat, homogeneous land surface for a control simulation. Using the Regional Atmospheric Modeling System, an instance of weak linear convection was simul...

UHD phenomena demand a modification of the presently established scientific methodology. This modified methodology concerns special care that should be taken into account while planning and performing experiments also way results (be they positive or negative) are interpreted. The proposal new is based on theoretical knowledge stemming from in bioelectromagnetics, ordered state water behind dis...
