Spatio-Temporal Lightning Analysis Over North Sulawesi in 2019 - 2020

Abstract

This study aimed to analyze the spatial and temporal lightning distribution in North Sulawesi. The general meteorological condition of North Sulawesi has also been considered to identify the cause of the lightning occurrence. Lightning activity over North Sulawesi has been investigated using lightning data from Winangun Geophysical Station during 2019-2020. The result shows that in the land area of North Sulawesi, the highest lightning density occurred in the Tomohon regions due to its topographical features. Overall, the flash density over the land area is higher than the sea area due to its high atmospheric instability. The maximum flash density does not occur during the wet periods, but it occurs during September - October – November, which has a high surface temperature over this region. It is also known that shearline and low-pressure areas contribute to the high lightning occurrence in October 2019, while La Nina in the Pacific Ocean influences lightning activity in July 2020

Spatiotemporal Evaluation of Pulmonary Tuberculosis Case in Karang Intan District, South Kalimantan, 2020-2021

“…Therefore, high humidity has a relationship to pulmonary TB transmission because it plays a role in the growth of tuberculosis bacteria (H. H.D. Lasari, Medyna, Fadillah, Rosadi, & Fakhriadi, 2023). The results of research by Nurdiana et al (2018) showed that there was a significant relationship between humidity and the transmission of pulmonary TB in family members with a P-value = 0,017 (p < 0,05) (Nurdiana, Haidah, & Nerawati, 2018).…”
