Abstract
A brief description of general tendencies in the outburst behaviour of 27 well-observed dwarf novae is given. The division between wide and narrow outbursts is very common, about 75% of all dwarf novae in the sample display such a bimodal width distribution. The total outburst width increases, the width ratio (of wide to narrow outbursts) decreases, with orbital period. Anomalous outbursts with abnormally slow rise gradients are also very common, 70% of the sample dwarf novae show them, at least occasionally. There is an exclusive distinction between normal and anomalous outbursts, as demonstrated in the case SS Cyg. Some other peculiarities, such as small peaks and micro-variability during Z Cam standstills, are also discussed.
