The Pacific Climate Change Science Program (PCCSP) was developed to assist decision makers and planners in 14 Pacific island countries and East Timor to understand better how their climate and oceans have changed and how they may change in the future.
This dataset hosts all resources that were developed through the collaboration between Tonga and PCCSP regarding changes in Tonga's climate
raw rainfall data collected in 2016
Data from the Tonga Meteorological Office.
10 year data series of :
i. Wind Speed
ii. Rainfall
iii. Mean Temperature
This study addresses rainfall trends, the frequency of droughts, La Niña influences and the relationship between rainfall and Sea Surface Temperature (SST) in Tuvalu. The findings revealed that;
* de-trended rainfall time series show declining trends in all four rainfall stations over the period 1953-2012;
* the frequency of drought ranges from three to fourteen years with a mean of nine years
* the occurrence of drought appears to follow the La Niña years
* boplots provide an effective option for defining drought
