Objective analysis schemes and their applications to hail measurements network in the Greek NHSP

Abstract

 The objective of this study is to present the investigations and applicability of several objective analysis schemes and to create a detailed, representative and better resolution grid-point hailpad network system retrieved from actual hailpad measurements. The main motivation for this study is the desire to use the equally spaced hailpad measurements in order to be able to theoretically estimate the appropriate hailpad spacing by using either the Monte-Carlo simulation method or any conventional method of statistical analysis.

To meet the goal, several objective analysis methods are applied to the actual hail impact energy measurements which were obtained from the hailpad network system in the Greek NHSP during the 21^st of June 1987 case study, and their effectiveness for the creation of an artificial grid-point hailpad network system is examined. Finally, comparisons between the methods themselves, and each of them against the actual hail impact energy measurements are performed, in order to determine the adequate objective analysis scheme.
