چکیده
The study examines long-term changes and short-term fluctuations in ambient temperature of North East India during 1901-2003 located in part of the Eastern Himalayan region of the Brahmaputra Basin. Long-term linear trends were examined with the Mann-Kendal rank statistic and moving average method while the short-term fluctuations were studied by applying Cramer’s test. The results showed significant warming trend in annual and seasonal maximum temperature. Decrease in minimum temperature during monsoon season and its increase during post-monsoon and winter season is evident. Higher magnitudes of linear trends are observed in the maximum temperature than in the minimum temperature. Maximum temperature showed increasing tendency in the recent five decades. On the contrary, minimum temperature decreased sharply during 1960-90. ∗ r.deka, chandan)@iitg.ernet.in

متن کاملTrend analysis and detection of precipitation fluctuations in arid and semi-arid regions
The most important impacts of climate change relate to temperature and precipitation. Precipitation is particularly important, because changes in precipitation patterns may lead to floods or droughts in different areas. Also, precipitation is a major factor in agriculture and in recent years interest has increased in learning about precipitation variability for periods of months to annual and s...
متن کاملClimatic elements, discharge and groundwater trends over time using Mann-Kendall Test in the Mighan Sub-basin of Arak
This study was an analytical research across 84 meteorological stations, performed in the Mighan sub-basin over a fifty-year study period (1961–2011).This research seeks to answer the basic question of how declining streamflow, increasing temperatures, and fluctuation in precipitation have impacted water resource allocation in the Mighan sub-basin. The research method is analytical based on Man...
متن کاملA role for atmospheric CO2 in preindustrial climate forcing.
Complementary to measurements in Antarctic ice cores, stomatal frequency analysis of leaves of land plants preserved in peat and lake deposits can provide a proxy record of preindustrial atmospheric CO(2) concentration. CO(2) trends based on leaf remains of Quercus robur (English oak) from the Netherlands support the presence of significant CO(2) variability during the first half of the last mi...
متن کاملA human disease indicator for the effects of recent global climate change.
C between weather and disease are well established, with many diseases occurring during certain seasons or erupting from unseasonable f lood or drought conditions. With new concerns about global warming, accompanied by greater climate variability, many recent studies have focused on disease fluctuations related to short-term or interannual climate oscillations (e.g., from weather extremes drive...
