The authors regret that in the above-mentioned article, the expressions of Eqs. (9), (10d) and (10e) are incorrect. The correct forms of these formulae are presented as follows: F…xuY # y0 † ˆ

F…x; y† F…y†

  ˆ F…x†·exp 2u·

1 1 1 lnF…x† lnF…y0 †

In addition, the joint return period Tx,y of X and Y represented by Eq. (10c) is the return period associated with the event …X . x; Y . y; or X . x and Y . y† that at least one of x and y is exceeded.
