A ground-based microwave radiometer gives the possibility of providing continuously available temperature and humidity profiles of the troposphere, from which instability indices of the atmosphere could be derived. This paper studies the possibility of correlating the radiometer-based instability indices with the occurrence of intense convective activity, namely, the occurrence of lightning. Th...

In the field of sensitivity analysis, Sobol’ indices are widely used to assess importance inputs a model its output. Among methods that estimate these indices, replication procedure is noteworthy for efficient cost. A practical problem how many evaluations must be performed guarantee sufficient precision on estimates. The present paper tackles this issue by rendering iterative. idea enable addi...
