Temperature Variability trend and extremes in Coastal Ghana

Temperature variations affect many sectors of the economy such as health, agriculture, water resource management and energy. With global average temperatures increasing, Ghana is vulnerable to the impact of increasing temperature variability. Despite the global highlights on temperature the current state of temperature variability, trends and extremes in Ghana was not clearly known.

Maximum temperatures from Ghana Meteorological Agency for the period 1960 and 2014 were used for this study. Analysis such as standardized anomaly, principal component analysis and extreme value decomposition carried out on the data look promising. In general, there is an increasing trend of maximum temperatures for all stations except Ada, an indication of global warming signature. The work is ongoing and will be published in a good journal.
