    Abstract: Aims: To explore the association between observed frequency of anticyclones over subtropical Indian Ocean (10°S-50°S, 102.5°E-142.5°E) and average autumn rainfall over the districts of Tasmania. Methodology: We have divided the rainfall amounts over nine districts of Tasmania into three categories (Above average, average and below average rainfall) by using z-scores technique for each autumn (March-May) month for the period of 1951-2016. We have also categorized the calculated frequency of anticyclone over the subtropical Indian Ocean in a similar fashion. Results: Our analysis suggests inverse association between each category of average rainfall and the corresponding frequency of anticyclones for each month of autumn. This association revealed that during below average rainfall, the high frequencies of anticyclones were occupied over the most of the area of subtropical Indian Ocean that resulted less rainfall in the districts while during above average autumn rainfall, the high frequencies of anticyclones observed in the west of 110°E this enabled more autumn rainfall over the districts. We have also found the negative correlation coefficients between mean sea level pressure over the same domain of Indian Ocean and average rainfall over each district in each month of the autumn (March-May). Conclusion: The slightly shift of Mean Central Pressure (MCP) to the north from the west coast of Tasmania from March-May enabled the extra-tropical activity of rainfall systems. This causes enhanced rainfall during average and above average rainfall conditions than March-April over nine districts of Tasmania.

    Abstract: This study employ Wavelet analysis to investigate the winter (May-Aug) rainfall variability with respect to the intensity of Indian Ocean Subtropical High Pressure (IOSHPS) System and its longitude, Indian Ocean Subtropical High Longitudes (IOSHLN), positions. The physical relationship among these predictors and winter rainfall were analyzed using composites of atmospheric circulation patterns. We have found inverse association between IOSH indices and winter rainfall. We have observed that maximum rainfall variability occurred in 1-3 years periodicity during 1951-1979 when IOSHPS was located around Southern Australia. This caused moisture onshore and Victoria received more rainfall. We have also observed that highest variability from 1980-2016 with similar periodicity in IOSHPS. The shifting of IOSHPS from Southern to Southeastern Australia and increase in its intensity from the post 1979 period of the analysis era (1951-2016) cause further declined in winter rainfall over Victoria.

    Abstract: This minireview provides a summary of the main findings, features, as well as limitations and gaps in the current epidemiologic research on COVID-19 vaccine hesitancy (VH) in Pakistani population. For this purpose, data on VH studies were extracted from January 2020 to October 2021, using a systematic review and meta-analysis approach. Literature review and other narrative studies were excluded. There exists a significant heterogeneity in the reported vaccine hesitancy in the population (pooled estimates from random-effects meta-analysis: 35% (95% CI, 28–43%). However, none of the co-variables included in the studies explained the observed variance/heterogeneity in the moderator analysis models. In this minireview and critical appraisal of current VH research, we conclude that an in-depth analysis of COVID-19 vaccine hesitancy in a representative sample of Pakistani population is crucial to measure the magnitude of VH as well to explore and identify the determinants of VH in Pakistani population. This is an important step toward informing intervention and policy design and to address this issue at its root cause. To this end, focused, methodologically robust and hypothesis-driven VH research is needed using a wide range of co-variables to support a detailed coverage of the individual and environmental level VH attributes.
