[ 1 ] - Reconstruction of Data Gaps in Total-Ozone Records with a New Wavelet Technique
This study introduces a new technique to fill and reconstruct daily observational of Total Ozone records containing void data for some days based on the wavelet theory as a linear time-frequency transformation, which has been considered in various fields of science, especially in the earth and space physics and observational data processing related to the Earth and space sciences. The initial c...
[ 2 ] - Dynamics and Thermodynamics Analysis of Tropical Cyclone Haiyan
Tropical cyclone Haiyan (TCH) that formed over the West Pacific Ocean during 3-11 November 2013 has been investigated using three datasets produced by Japan Meteorology Agency, ECMWF and NCEP. Strength of TCH has been studied using two synoptic parameters of 10-m wind velocity and mean sea level pressure (MSLP). Following, three dynamic parameters including vertical wind shear (VWSH) vector, he...
