| Abstract | Meteors are an important source for the metal atoms of the upper atmosphere metal layers and for meteoric dust in the upper mesosphere and lower thermosphere. Five SKiYMET meteor radars at locations between 69 ̊N and 35 ̊S have been used to study the annual and diurnal variations of meteor rates and their latitudinal variability. We report on the observed diurnal variations (averaged over one month) of meteor rates and their significant variations throughout the year. The ratio of maximum over minimum rates throughout one diurnal cycle is increasing with decreasing latitude and reaches values of about 2.3 at 69 ̊N, of 4.6 at 54 ̊N, of 6.4 at 22 ̊S, and of 5.6 at 35 ̊S. The annual variation of meteor rates is described as follows: A strong peak of meteor rate is found for the month June at high and middle Northern latitudes, whereas the meteor rates peak at low Southern latitudes in June and December. |
