Statistical analysis of rainfall trend and water vapor distribution over the Central African Republic
To apprehend the temporal and spatial distribution of the rainfall over CAR, we computed thirty-three years (1981-2013) of monthly rainfall, relative humidity over the country divided into four (4) distinct sub-regions. Bearing different characteristics one to another, we found that Region 2 and Region 4 were having a statistical significant upward trend along the long term rainfall variation; meanwhile Region 3 was the one having a highest coefficient of variation on the yearly basis. The composite analysis showed that December, January and February were the months with higher frequency of va ...
Ocean, climate and weather: the role of the World Meteorological Organization
When it comes to the weather, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture: covering some 70 per cent of the Earth’s surface, the ocean is a major driver of the world’s weather and climate. The ocean is also a major driver of the global economy, carrying more than 90 per cent of world trade and sustaining the 40 per cent of humanity that lives within 100 km of the coast. Recognizing this, national weather agencies and researchers regularly monitor the ocean, model how it affects the atmosphere and deliver m ...

Operational Models Encyclopedia
The availability of numerical guidance from NWP models has been an important component of operational forecasting for decades. For many, the output from this numerical guidance was produced by a mysterious “black box”. Rules for using and adjusting the guidance for operational forecasters were often subjective “Rules of Thumb” based on experience rather than based on quantitative analysis. To open up this “black box”, we produced this web-based “Operational Models Encyclopedia” linking both generic information on how NWP models work, and specifics on physical parameterizations, dynamics, and d ...
