What the literature leaves open

  • Technical challenges include avoiding the need to assume hydrometeor fall speeds en route to estimates of vertical air motion. Domain challenges include understanding the variability of fall speed estimates in different storm environments.

    Dual-frequency profiler study of hydrometeor fall speeds in tropical deep convection · 2026 · DOI

  • There is a need to understand the synoptic drivers and upper air environment of catastrophic flood events in southeastern Poland. The relationship between climate change and flood risk is not fully understood.

    Extensive floods in south-western Poland: Synoptic drivers, upper air environment and associated impacts · 2026 · DOI

  • The study does not address the potential impact of other climate variables on precipitation regimes. The robust trimmed k-means approach may not be applicable to all types of climate data. The study is limited to annual precipitation series from 81 stations in Türkiye.

  • The lack of comprehensive and reliable precipitation data in the region.

  • The need for a comprehensive evaluation of precipitation behavior using advanced trend analysis techniques. The lack of understanding of climate-related hydrological variability in the Eastern Black Sea Basin.

  • The use of observed auxiliary predictors for post-processing medium-range precipitation forecasts remains largely unexplored. The temporal gap between present observations and future precipitation at medium-range lead times is a challenge.

    Moisture Source–Receptor Relationships for Post-Processing Medium-Range Precipitation Forecasts · 2026 · DOI

  • Future work should address these limitations by calibrating the disaggregation parameter with longer local pluviograph records, radar-derived rainfall estimates, satellite precipitation products, or stochastic storm profiles representative of tropical convective rainfall.

    Reconstructing IDF curves from daily rainfall records in data-scarce regions: A statistical method based on temporal disaggregation and gumbel modeling · 2026 · DOI

    A Study on the Application of Google Earth Engine for Precipitation Monitoring · 2026 · DOI

  • The temporal dynamics of storm intensity and persistence at the intraday scale in southern Brazil are not well understood. There is a need for detailed analyses of the temporal and probabilistic characteristics of extreme events in the region.

    Hourly-scale modeling of storm transitions in Southern Brazil with Markov Chains · 2026 · DOI

  • Quantifying the extent to which this influences substantive conclusions was beyond the scope of this study, but represents an important direction for future work. The key limitation is therefore not disagreement in relative ordering, but in how that ordering is translated into categorical or aggregated interpretations.

    Critical assessment of metrics and methods used to quantify temporal loading of rainfall events · 2026 · DOI

  • However, the seasonal variability in SSF is rarely examined explicitly, as most SSF studies are based on short observation periods and thus only cover a limited number of events.

  • The research highlights the need for a comprehensive approach to assessing climate change impacts on water budgets.

    Indice-Based Characterization of Precipitation Variability Using Multiple Trend Analysis Methods in the High-Rainfall Eastern Black Sea Basin, Türkiye · 2026 · DOI

  • Prior work has focused on retrieving vertical air motions, but not bulk radar reflectivity-weighted hydrometeor fall speed.

    Dual-frequency profiler study of hydrometeor fall speeds in tropical deep convection · 2026 · DOI

  • High-frequency echo structures are easily over-smoothed by deterministic sequence models. The task requires capturing temporal dependencies, echo displacement, and multiscale spatial structures.

    Short-Term Precipitation Forecast Based on Diffusion Spatiotemporal Network · 2026 · DOI

  • The study only considers a limited range of wind speeds (9-11 m/s). The study only uses data from a single location (Universiti Teknologi Malaysia, Kuala Lumpur). The study does not consider other factors that may affect mm-wave propagation, such as atmospheric conditions.

  • To explore the use of other observational datasets with near-global coverage and less than 1-day latency. To evaluate the performance of the proposed methodology in other regions.

    Moisture Source–Receptor Relationships for Post-Processing Medium-Range Precipitation Forecasts · 2026 · DOI

  • This is a property of the design, not a recalibration claim: the numerical values for the GPD threshold, alpha, and saturation count remain region specific, but the framework’s graceful degradation under sparse data is general.

    A Modular and Transferable Framework for Enhancing Satellite-Derived Daily Precipitation: Adjusting Values, Aligning Distributions, and Preserving Extremes · 2026 · DOI
