    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... More

  • Causal Relationships between Monsoon Systems, the Mascarene High, and Rainfall Variability over Botswana, Southern Africa

    Lydia Onoziba Frank, Pradhan Parth Sarthi
    129-146

    Article ID: 6190
    301  (Abstract) 149  (Download)

    Abstract: Climate change and variability pose significant threats to southern Africa, with projected continuous drought in Botswana. This study examines the causal relationships between African-Indian monsoon systems (East Africa, West Africa, and Peninsula India), the Mascarene High, and interannual rainfall variability over Botswana. Using statistical analysis and mapping techniques (Pearson correlation statistics and convergent cross mapping... More

    Abstract: A multi-model ensemble from the new CMIP6 models was utilized to determine the future changes in precipitation over Southeast Asia (SEA; longitude: 90°E–140°E, latitude: 15°S–30°N). The changes are computed for the three (3) future time slices (2021–2040, 2041–2060, and 2081–2100) under four (4) different scenarios based on the Shared Socioeconomic Pathways (SSPs): 1-2.6, 2-4.5, 3-7.0,...
