the geographical distribution of growing degree-days (gdds) within iran was studied using gis-based maps. gdds were calculated using daily thermal parameters (daily maximum and minimum air temperature). based on the purpose of the study and climatic conditions of iran, the average value of 5?c was chosen for gdd calculation. the calculations were carried out using daily weather data of 113 mete...

Crater degradation on Mars is a key to understand erosion through time. Strongly eroded craters in the highlands are interpreted to be the result of enhanced erosion rate during the Noachian epoch [1]. While fluvial valleys climatic meaning and duration are still difficult to define (strongly warmer climate or episodic activity under slightly warmer climate), the enhanced Noachian craters degra...

The practical utilization of available modern as well as traditional weather forecasting systems builds herders' resiliency capacity to climatic shocks. The precision and reliability of the forecasting system determines its creditability and acceptance by the users to be proactive in the decisions they make based on the forecasted information. It has been postulated that traditional weather for...

the goal of this research is the determining of planting date and providing agricultural calendar for corn in kermanshah province using climatic elements of temperature and rain fall. so, at first, long term  climatic statistics are collected from 2001 to 2011  and then  considered to temperature and rain fall parameters like  absolute maximum and minimum  in region during growth period, planti...

Powerful software tools are used by the aerospace and power generation communities to check codes for errors. The Software Validation Project at Edge Hill University (http://www.edgehill.ac.uk) in collaboration with SimCon Ltd (http://www.simconglobal.com) has applied these tools to WRF, the most widely used program for modeling climate and weather. Preliminary results have been generated. Alth...

OBJECTIVE To examine the links between the quality of life (QOL) and season and weather conditions in ankylosing spondylitis (AS) patients. METHODS A cohort of 146 AS patients (67% males), with a mean age of 47.3 years and a mean disease duration of 12.8 years, answered a self-administered questionnaire, the AS-AIMS2 validated for AS, 4 times over a period of one year in a postal survey. Clin...

Understanding the climate and location aspects are usually the first step in energy applications e from buildings to renewable energy. With so many of the renewable energy sources being significantly dependent on weather, it is essential that the temporal and geospatial variability and distribution of climatic design parameters are investigated for effective planning and operation. ASHRAE-HOF i...
