Summary:Records of the occurrence and duration of Saharan dust events over Tel Aviv and Ramat Hasharon, over a period of 33 yr, were statistically analyzed, and probabilities were calculated. The results show the following. 1. (1) The probability for a dust episode (large amounts of suspended dust, wet fallout and reduced visibility) to occur on a random calendric day increases from autumn to winter, remains steady during most of the winter, rises to a peak in April, and decreases sharply toward summer. 2. (2) Eighty-one percent of the dust episodes lasted 1 d, about 13% lasted 2 d. The longest dust episode lasted 6 d. The probability of having a week with a dust storm is fivefold greater than for a random calendric day.
