Abstract: Haboob occurrence strongly impacts the annual variability of airborne desert dust in North Africa. In fact, more dust is raised from erodible surfaces in the early summer (monsoon) season when deep convective storms are common but soil moisture and vegetation cover are low. On 27 June 2018, a large dust storm is initiated over North Africa associated with an intensive westward dust transport. Far away from emission sources, dust is transported... More

Abstract: A review of the state of knowledge and phenomenology on the site of the greatest atmospheric electrical activity in the world, known as the Catatumbo Lightning, located southeast of Lake Maracaibo (Venezuela), is presented. A microphysical model is presented to explain the charging process through electrical displacement within the cells of the cloud, incorporating the role of the self-polarization of ice and methane molecules as pyroelectric...

Abstract: With the development of the time and the progress of economy, great changes have taken place in the environment. In recent years, it is common to see bad weather, such as hurricane, drought, lightning and so on. The emergence of these weather has the greatest impact on farmers and crops, especially the lightning weather, not only that, but also sometimes cause personal injury.

Abstract: In the present review article human diseases caused by various groups of pathogens have been explained with its etiology, epidemiology and treatment. In addition, effect of climatic changes on parasites and pathogens has been demarcated with rising incidences of diseases. In response to environmental changes, mainly external and internal microenvironment of body and drug regimens taken by patients; virus is regularly changing its form and new... More

Abstract: This article examines the off season rainfall in northern coast Tanzania (NCT) including Zanzibar which occurred in January and February 2020 (JF). Like the JF rainfalls of 2001, 2004, 2010, 2016 and 2018, the JF (2020) rainfall was more unique in damages including loss of lives, properties and infrastructures. The study used the NCEP/NCAR reanalysis data to examine the cause of uniqueness of JF rainfall in 2001, 2004, 2010, 2016, 2018 and 2020... More
