MARC recordOn the use of lognormal statistics to simulate one- and two-dimensional under-ice draft profiles / B.A. Hughes.
| Title: | On the use of lognormal statistics to simulate one- and two-dimensional under-ice draft profiles / B.A. Hughes. |
| Author(s): | Hughes, B. A. |
| Date: | 1991. |
| In: | Journal of Geophysical Research. (1991.), Vol. 96(C12) (1991) |
| Abstract: | Probability density function of one-dimensional measurements of ice draft is shown to be fitted accurately by set of lognormal distributions. Also describes technique for generating synthetic ice-draft data by interspersing filtered random number sequences drawn from fitted lognormal distributions. Sequences are interspersed by random selection to produce one- and two-dimensional model ice-draft profiles. Filter characteristics can be chosen so that one-dimensional spectra of model profiles agree well with measurements. For features with horizontal length scales >10 m, realizations of ice-draft data are in good visual agreement with measured profiles. |
