ABSTRACT. A review is presented of the radar observation of tropical cyclones in the Indian seas. The use of radar in operational cyclone tracking and forecasting as well as the knowledge gained from radar observations of the structure, wind and rainfall distribution and motion of cyclones are discussed. In the context of the expected introduction of operational Doppler ra1ars in India, the future prospects in the use of radar for operations and research are outlined. Some important areas where our understanding of cyclones can be improved by studies with radar in conjunction with other observations are listed.

The purpose of this article is to discuss the trajectory of Belarusian-Lithuanian relations with a particular focus on the period after the 2020 Belarusian presidential election, which resulted in a change in international relations in the region. This was the moment that redefined the Lithuanian-Belarusian relations, which until 2020 were satisfactory for both sides (especially in the economic aspect). However, Lithuania began to pursue a reactive policy of promoting the democratisation of Belarus and provided multi-level support to Belarusian opposition forces. The current problems in bilateral relations (e.g., the future of Belarusian Nuclear Power Plant located in Astravyets) have been put on the agenda for discussion at the EU level, while the instruments of a hybrid conflict in the form of an influx of immigrants into Lithuania, controlled by the Belarusian regime, have become a key issue for the future prospects of relations between Belarus and Lithuania.

The Relationship

AbstractTRMM satellite 3B42 rainfall estimates for 133 landfalling tropical cyclones (TCs) over China during 2001–15 are used to examine the relationship between TC intensity and rainfall distribution. The rain rate of each TC is decomposed into axisymmetric and asymmetric components. The results reveal that, on average, axisymmetric rainfall is closely related to TC intensity. Stronger TCs have higher averaged peak axisymmetric rain rates, more averaged total rain, larger averaged rain areas, higher averaged rain rates, higher averaged amplitudes of the axisymmetric rainfall, and lower amplitudes of wavenumbers 1–4 relative to the total rainfall. Among different TC intensity change categories, rapidly decaying TCs show the most rapid decrease in both the total rainfall and the axisymmetric rainfall relative to the total rain. However, the maximum total rain, maximum rain area, and maximum rain rate are not absolutely dependent on TC intensity, suggesting that stronger TCs do not have systematically higher maximum rain rates than weaker storms. Results also show that the translational speed of TCs has little effect on the asymmetric rainfall distribution in landfalling TCs. The maximum rainfall of both the weaker and stronger TCs is generally located downshear to downshear left. However, when environmental vertical wind shear (VWS) is less than 5 m s−1, the asymmetric rainfall maxima are more frequently located upshear and onshore, suggesting that in weak VWS environments the coastline could have a significant effect on the rainfall asymmetry in landfalling TCs.

The Future

ABSTRACT A variant of downscaling is devised to explore the properties of tropical cyclones (TCs) that originate in the open ocean of the western North Pacific Ocean (WestPac) region under extreme climates. This variant applies a seeding strategy in large-scale environments simulated by phase 5 of the Coupled Model Intercomparison Project (CMIP5) climate-model integrations together with embedded integrations of Coupled Ocean–Atmosphere Mesoscale Prediction System for Tropical Cyclones (COAMPS-TC), an operational, high-resolution, nonhydrostatic, convection-permitting numerical weather prediction (NWP) model. Test periods for the present day and late twenty-first century are sampled from two different integrations for the representative concentration pathway (RCP) 8.5 forcing scenario. Then seeded simulations for the present-day period are contrasted with similar seeded simulations for the future period. Reinforcing other downscaling studies, the seeding results suggest that the future environments are notably more conducive to high-intensity TC activity in the WestPac. Specifically, the future simulations yield considerably more TCs that exceed 96-kt (1 kt ≈ 0.5144 m s−1) intensity, and these TCs exhibit notably greater average life cycle maximum intensity and tend to spend more time above the 96-kt intensity threshold. Also, the future simulations yield more TCs that make landfall at >64-kt intensity, and the average landfall intensity of these storms is appreciably greater. These findings are supported by statistical bootstrap analysis as well as by a supplemental sensitivity analysis. Accounting for COAMPS-TC intensity forecast bias using a quantile-matching approach, the seeded simulations suggest that the potential maximum western North Pacific TC intensities in the future extreme climate may be approximately 190 kt.

Anti-Muslim emotions are not new for the world. It was present since the rise of Islam. West was furious after facing Muslims in battle ground and constantly defeated by those who were less equipped but obtained high morals. Initially they were frightened due to the novelty and unique approach of faith and its execution, therefore, they try to fabricate the original manuscripts, making false stories and molesting the last prophet’s life history. Islamophobia transformed after 9/11 and become more intensified and dangerous. It effected the common men worldwide without any boundaries. The respective research is based on the fact that hatred is the negative notion whether it related with nobility or wicked perception. It creates harmful effects on human psychology which subsequently created abusive mindset and actions. When any form of ideology identified as phobia means uncontrolled envy combine with the concept and turn it into a form of frenzied connotation. The fight between East and West was ancient which now convert among religions particularly Islam and others. The research is intend to provide the journey of anti-Islamism from past to present as well its significant elements and its present state. It also discusses the future prospects of clash of religions.

AbstractThe purpose of this paper is to investigate the key economic and geographical characteristics of the investment development of Belarus and how these characteristics could evolve in the future. The evaluation of the investment development of Belarus is based on comparative economic analysis, spatial analysis research methods and the cartographic method. Our results indicate a stable, predictable and enabling investment policy as the main determinant for attracting investment. This is confirmed by changes in the spatial distribution of foreign investment inflows in the real economy of Belarus by countries for 2010 and 2018. The characteristics of Belarusian investment development are identified because of the need to intensify innovative performance in the strategic dimensions of sustainable development. Particular attention is paid to the development of special economic zones with preferential regimes in the Republic of Belarus. This paper provides important new insights into the future prospects for Belarusian investment development on the basis of identified specifics.
