چکیده
(2) Downward infrared radiation Measurements of downward infrared radiation have been conducted since the early 1990s at Tsukuba. A time-series representation of five-year running mean downward infrared radiation until 2010 shows an increasing trend at a rate of about 0.4 W/m per year (Figure 3.3-5). This is consistent with the trend seen in the results of analysis using data from all BSRN stations worldwide (+0.3 W/m per year) (WCRP, 2010).

Statistical Downscaling HadCM3 Model for Detection and Perdiction of Seasonal Climatic Variations (Case Study: Khabr Rangeland, Kerman, Iran)
Rangelands are one of the most vulnerable parts concerning the climatechanges‟ impacts. These impacts are even stronger in the arid and semi-arid areas whererangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out theactual dynamics of climate variations on the rangelands. The aim of this research was todetermine climate changes in Khabr rangeland, Kerman, Iran. S...

متن کاملEffect of Short- and Long-term Memory on Trend Significancy of Mean Annual Flow by Mann-Kendall Test
Climate variability and change is threatening water resources around the world. One hundred and fourtheen (114) stations from Reference Hydrometric Basin Network (RHBN) around Canada with at least 30 years continuous data (up to 2011) were selected to study the trend in mean annual runoff for different periods of 30 to 100 years in step 10 years by non-parametric Mann-Kendall test. Effect of sh...

Abstract Long-term observational data are essential for detecting and understanding local, regional and global climate change. The goal of this paper is to consider climate data of west of the Caspian Sea for any trends in Annual means of 2m temperature and precipitation at the stations of Anzali, Rasht, Astara and Lahijan for 1956-2018 period. Some inconsistencies in the data were found. Our ...
