title: [Suicidal behavior and meterological conditions].
abstract: Six hundred and seventy five cases of attempted suicide observed in a resuscitation department were confronted with a certain number of biometeorological factors recorded daily: atmospheric pressure, air temperature, degree of insolation, precipitation, relative humidity, water vapour pressure, wind (speed and direction), hydrometeores, index of solar eruption, density of F2 layer. The confrontation is made for the two days before the intoxication and for the day when suicide is attempted. Parameters are then studied by statistical calculation (calculation of X2 and of the number of degrees of freedom). There does not seem to be any significant relationship, in spite of disconcerting series, between most meteorological factors and the number of attempted suicides observed. However, it is noted that no suicides were recorded during periods of solar eruption, and that there seems to be a marked correlation between suicide and winds, particularly according to their direction. Thus, winds charged with ionised particles seem to coincide with a high rate of self-destruction.
