| Summary: | 'indicated in the Egyptian stations, but warming is greater across the region. The diurnal temperature range is addressed. Because most series in this region lack adjusted. Typically, globally averaged or hemispherically analysis of thermal trends. These series are generally from annual temperatures, but more recent studies have considered arise from either abrupt or gradual discontinuities. at Khartoum, Sudan than the surrounding stations. Finally, averaged annual mean land temperature series are used for continuity, the methods commonly used in climate studies in continuous, relatively homogeneous time series. Unlike the decreasing, while changes in the maximum temperature vary. extra-tropics, these series are not widely available in the factors are common in most series. These influences can histories, a statistical technique, or both. Once these homogeneity in the series. Averages of the first ten and homogeneity is applied to the series to ensure relative identified. The results show that no unusual warming is in the ten-year means are significant. A F-test is also used inhomogeneities are identified the original series is inhomogeneities must be identified through either station last ten years are then calculated, and a difference is maximum and minimum temperature series. However, most of maximum and minimum temperatures over smaller scales in the modification. Northeastern Africa from 1900 to 1950, the data are analyzed obtained. A t-test is used to determine if the differences present. With access to previously unavailable data from Research in climate change requires the use of long, rural stations, possible trends due to urbanization can be significant warming in the minimum and mean temperatures the extra-tropical regions cannot be applied without some the extra-tropics. Early studies generally focused on mean the problems that arise in a typical tropical area are Therefore, in order to minimize non-climatic influences, the these studies are on data from the extra-tropics from 1950 to to compare the variances. The results show that there is to determine whether thermal patterns are identifiable in tropics and sub-tropics. First, the Alexandersson Test for tropics and sub-tropics. Influences due to nonclimatic When series from large urban stations are compared to smaller |
