| Summary: | a temperature series with one significant break has a addressed by some researchers, but only as a mention that the addressed this homogeneity problem have only tested "average" adjustments show a seasonal pattern and when summed, equal analyzed must be homogeneous. A homogeneous time series is and applies it to mean monthly maximum and minimum constant variance throughout its entire record. An F-test is discontinuity occurs and whether or not it is significant. A discussed and applied to selected series, and it is shown for the individual months. In addition, the monthly in the Alexandersson test. The practical aspects studied include data type and temporal comparisons. The results of means or annual is not always the same break point found in months respectively. Finally, an adjustment procedure is obtain the most definitive results, the time series being one in which trends and variations are caused by effects of Plains. The Alexandersson test locates where a break or results may contain some biases due to the inhomogeneities in significant difference between them. The results show that some series do not have a constant variance throughout and such as the study of global climate change. In order to temperature data from 22 stations in the Northern Great that station's maximums or minimums and each individual that the annual adjustment is not the same as the adjustment the annual adjustment. the data being studied. In addition, researchers that have theoretical and numerous practical aspects are examined. The theoretical aspect studied is the question of whether or not There are many research problems facing climatologists today, these analyses show that a break point found in a station's this difference may effect the standardization procedure used time series such as the means and the annuals. This thesis used to compare the variances and determine if there is a utilizes a homogeneity test developed by Alexandersson (1986) weather and climate. The concept of homogeneity has been |
