TMA director general Agnes Kijazi told reporters in Dar es Salaam that the changes should be noted by climate-sensitive sectors such as construction, agriculture and manufacturing.
“Players in these sectors should not go about their activities as usual; they should adapt to cope with the changes,” she said.
Kijazi said in 2019, the country annual mean temperature was 23.8 °C, which is 0.8 °C warmer than long-term average, adding that this warming in 2019 is ranked the fourth highest on record since 1970.
Dr Kijazi said the main of the climate status was to enhance awareness and understanding of climate variability and change among stakeholders for enhanced action.
She added that another aim was to provide analyses of weather and climate events that occurred over different parts of the country by placing them into historical perspectives to save as a monitoring tool for climate variability and change on annual basis.
“The 2019 statement is the ninth issue in the series of climate statements issued by TMA since 2011,the Statement saves as an effective mechanism for contributing and complimenting to the World Meteorological Organization (WMO) State of the Global climate report and global efforts for enhanced action on climate monitoring,” she said.
On the other hand, in 2019 the country received higher amount of rainfall placing it the fourth in historical records since 1970.
“The average annual rainfall was 1283.5 mm, which is 125 per cent of the long-term (1981-2010) average and higher than long-term average rainfall by 256.5 mm,” she said.
Most part of the country received above normal rainfall during October–December (Vuli) 2019 rainy season, ranking it the second wettest Vuli on record since 1970 and October 2019 was the wettest October ever since 1970. However, rainfall in March –May (Masika) 2019 was normal.
March and April 2019 were the warmest months of the year with country mean temperature higher than long-term average by 1.1 °C and 1.6 °C respectively.
Since 1970 there were 13 events of above normal Vuli rainfall and only four events of above normal Masika rainfall and the year 2003 was the driest year on record since 1970.
“Over the last two decades, from 1995, the country experienced an increasing trend in temperature with minimum temperatures night temperatures warming more than maximum temperatures during daytime,” she said.
