Normal distribution to repeat the barrier barotrauma over Iraq Winter

Abstract

Respect to the subject of research the phenomenon of occurrence of blocking over Iraq and occurrences happen for the duration of the (1985-2016) during the winter. There is no doubt that this issue is of great importance due to its impact on climate elements in the study area like temperature and rainfall in winter. Has been calculated occurrences happening tracking maps liturgical lines equal to the high pressure of 500 millibars from the website through (Vortex Plymouth weather center). It was recorded occurrences of occurrence of the phenomenon over Iraq for the winter months (December, January, February) and the representation of these duplicates in a statistical table, and then worked as a graphic forms per month. It was calculated probability of occurrence of the phenomenon of the blocking over Iraq winter for a hundred years depending on the normal distribution of Poisson's equation.
