Each week the Ministry of Transportation kindly sends to me the precipitation records from its 69 weather monitoring stations across Kurdistan. As a result I have been able to compare the rainfall for the 6 month period from 11th October 2010 to 23rd April 2011 to that recorded over the same period the previous year (i.e. 11th October 2009 to 23rd April 2010). Comparing the rainfall in the four governorates reveals the following:
· Dohuk: For the 6 month period 2009 -2010 the 20 stations in Dohuk governorate recorded an average rainfall of 691.8 mm compared to 573.4mm in the same period for 2010-2011. The rainfall this season has been 118.3 mm less, i.e. a 17.1 % reduction.
· Erbil: Over the 6 months period 2009-2010 the average rainfall recorded by the 23 stations in this governorate was 518.4mm compared to 415.7 mm recorded in the last 6 months. This is a drop of 102.76 mm or 19.8%.
· Suliemaniah: The average rainfall recorded by the 19 stations in the governorate was 769.99mm in 2009-2010 and 422.2mm over the 6 months, 2010-2011. This is a drop of 345.78 mm or 44.9%.
· Garmyan: The 7 stations in this governorate recorded an average of 420.5mm rainfall in the 6 months of 2009-2010 while in the last 6 months the average was 241.4mm. This is a drop of 179 mm or 42.56% reduction.
Comparing the data collected over all four governorates one can see that the rainfall over the last 6 months is 31.09% less than that of the same 6 month season in 2009-2010.
