    9-15

    Article ID: 1859
    1860  (Abstract) 257  (Download)

    Abstract:

    Observed rainfall is a very essential parameter for the analysis of rainfall, day to day weather forecast and its validation. The observed rainfall data is only available from five observatories of IMD; while no rainfall data is available at various important locations in and around Delhi-NCR. However, the 24-hour rainfall data observed by Doppler Weather... More

    Abstract:

    The East China coast is one major cyclogenesis region of extratropical cyclones (ETCs) in boreal winter. In this study, the climatological characteristics of winter ETCs passing over the coastal water of China are analyzed by using clustering and composite analysis. Automated cyclone detection and tracking algorithm are used to identify the ETCs, which are further... More

    Abstract:

    Precipitation on the Tibetan Plateau (TP) has an important effect on the water supply and demand of the downstream population. Involving recent climate change, the multi-decadal variations of the impact of El Niño-Southern Oscillation (ENSO) events on regional climate were observed. In this work, the authors investigated the changes in summer precipitation over TP during... More

  • Snowfall Shift and Precipitation Variability over Sikkim Himalaya Attributed to Elevation-Dependent Warming

    Pramod Kumar, Khushboo Sharma
    1-26

    Article ID: 5854
    571  (Abstract) 241  (Download)

    Abstract:

    Sikkim Himalaya hosts critical water resources such as glacial, rain, and snow-fed springs and lakes. Climate change is adversely affecting these resources in various ways, and elevation-dependent warming is prominent among them. This study is a discussion of the elevation-dependent warming (EDW), snowfall shift, and precipitation variability over Sikkim Himalaya using a high-resolution ERA5-land dataset.... More

  • Relationship and Variability of Atmospheric Precipitation Characteristics in the North-West of Ukraine

    Svetlana Vasilivna Budnik
    30-40

    Article ID: 5657
    283  (Abstract) 154  (Download)

    Abstract:

    The paper deals with the issues of differentiation of atmospheric precipitation into gradations according to their characteristics and established meteorological practices. The division of atmospheric precipitation into gradations allows one to have an idea of the possible consequences of their fallout on life in the area. The dependence of the average intensity of precipitation on... More

  • Investigating the Effects of Madden-Julian Oscillation on Climate Elements of Iran (1980-2020)

    Kourosh Mohammadpour, Zahra Hejazizadeh, Hooshang Ghaemi, Mohammad Salighe
    21-32

    Article ID: 5351
    386  (Abstract) 189  (Download)

    Abstract:

    The Madden-Julian Oscillation is one of the large-scale climate change patterns in the maritime tropics, with sub-seasonal time periods of 30 to 60 days affecting tropical and subtropical regions. This phenomenon can cause changes in various quantities of the atmosphere and ocean, such as pressure, sea surface temperature, and the rate of evaporation from the... More

  • Spatio-temporal Changes in the Regime of Rivers in the Pripyat River Catchment and Climate Change

    Budnik Svetlana Vasilivna
    1-9

    Article ID: 4396
    409  (Abstract) 240  (Download)

    Abstract: In work features of a hydrological regime of catchments of the river of the Pripyat in climate change are considered. Researches of meteorological characteristics of the given territory show the tendency to growth, both temperatures of air, and precipitation, evaporation from a surface of water and ground also show the tendency to increase. That is... More

  • Long Term Spatio-temporal Variations of Seasonal and Decadal Aridity in India

    Pavan Kumar B, Bhavani Pinjarla, P K Joshi, P S Roy
    29-45

    Article ID: 3475
    809  (Abstract) 275  (Download)

    Abstract: A comprehensive analysis of climate data (1958-2018) is carried out at the national scale in India to assess spatiotemporal variation in aridity. The aridity is analyzed using UNEP (United Nations Environment Programme) Aridity Index (AI), which is the ratio between Precipitation (P) and Potential Evapotranspiration (PET). Freely available Terra-Climate database, P and PET variables, offered... More

    Abstract:

    Stratospheric Aerosol Injection (SAI) emerges as a geoengineering strategy to mitigate global warming by reflecting sunlight back into space. However, this approach raises significant concerns, particularly regarding its impact on rainfall characteristics in the Sahel. This study investigates the effects of injecting sulfur dioxide (SO2) into the stratosphere using the IPSL-CM5A-LR climate model, under two... More

    Abstract:

    The Intertropical Convergence Zone (ITCZ) is a key atmospheric system on a global scale, primarily driven by trade wind convergence near the equator. The ITCZ plays a crucial role in modulating the climate of the borders of tropical continental areas. For instance, Northeastern Brazil experiences a climate influenced by the ITCZ over the Atlantic Ocean.... More
