Mapping the Storm: Geospatial Impacts of Severe Weather on LEO Network Performance
Pith reviewed 2026-06-28 12:11 UTC · model grok-4.3
The pith
Severe weather like thunderstorms degrades Starlink performance for more than 55 percent of affected terminals, with outages lasting minutes to hours.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Severe weather events such as thunderstorms with heavy rain or snow have a pronounced effect on network performance; more than 55% affected terminals experienced substantial degradation, with sustained impairments or full service outages lasting from several minutes to multiple hours.
What carries the argument
Spatial join techniques that time-align terminal telemetry with classified high-resolution weather events to measure KPI changes.
If this is right
- Weather-aware provisioning can reduce service variability in LEO networks.
- Geospatial predictive models can incorporate weather-inferred performance data.
- Resilient system design can account for outage durations from minutes to hours.
- Service-level forecasting tools can integrate localized meteorological inputs.
Where Pith is reading between the lines
- The same spatial-join approach could be applied to other LEO constellations to test consistency of weather sensitivity.
- Network operators might use these patterns to prioritize backup capacity in high-risk weather zones.
- Regulatory benchmarks for broadband reliability could include weather-adjusted outage metrics.
Load-bearing premise
The 1,292 terminals and their telemetry provide a representative sample of network behavior under weather events, and spatial joins accurately align locations without significant misclassification.
What would settle it
A large independent sample of terminals during documented severe weather events showing degradation in substantially fewer than 55 percent of cases or no sustained outages beyond a few minutes.

LEO satellite constellations, led by deployments such as Starlink, are playing an increasingly pivotal role in enabling global broadband connectivity. However, the reliability and performance of these space-based networks are highly sensitive to environmental dynamics, particularly localized weather phenomena that exhibit strong spatio-temporal variability. In this study, we present a continental-scale geospatial analysis of weather-induced performance degradation in the Starlink LEO network, with a focus on the contiguous United States. Leveraging a unique dataset comprising more than 870,000 terminal hours of minute-level telemetry from 1,292 Starlink terminals, we integrate high-resolution localized weather observations to quantify the impact of various meteorological conditions. We evaluated key performance indicators (KPIs)-including ping latency, ping drop rate, and signal quality-using spatial join techniques and time-aligned correlation with classified weather events. Our analysis reveals that severe weather events, such as thunderstorms with heavy rain or snow, have a pronounced effect on network performance. In particular, more than 55% affected terminals experienced substantial degradation. Temporal continuity analysis at the minute level shows that such degradation can lead to sustained impairments or full service outages lasting from several minutes to multiple hours.This work contributes to the first large-scale empirical study linking LEO satellite Internet performance with fine-grained weather data in both space and time. Our findings offer actionable insights for geospatial predictive modeling, weather-aware network provisioning, and resilient satellite communication system design. We also propose a framework for incorporating weather-inferred performance variability into future geospatial planning and service-level forecasting tools for LEO-based Internet systems.

Referee Report
Summary. The paper conducts a continental-scale geospatial analysis of weather-induced performance degradation in the Starlink LEO network using minute-level telemetry from 1,292 terminals (870,000 terminal-hours) in the contiguous US. It integrates localized weather observations via spatial joins and time-aligned correlation to evaluate KPIs (ping latency, drop rate, signal quality), reporting that severe weather events such as thunderstorms with heavy rain or snow cause substantial degradation in more than 55% of affected terminals, with sustained impairments or outages lasting minutes to hours. The work positions itself as the first large-scale empirical study linking LEO performance to fine-grained weather data and proposes a framework for weather-aware modeling.
Significance. If the central observational correlations hold after methodological validation, the study would provide a valuable large-scale empirical dataset and framework for geospatial predictive modeling of LEO network resilience, with direct implications for weather-aware provisioning and system design. The scale of the telemetry corpus is a strength, but the absence of reported statistical methods or validation steps limits the current contribution to descriptive correlation rather than robust attribution.
major comments (2)
- [Abstract] Abstract: The headline claim that 'more than 55% affected terminals experienced substantial degradation' during thunderstorms/heavy rain or snow supplies no statistical methods, error bars, sample selection criteria, or validation steps. This prevents assessment of whether the fraction is robust or sensitive to confounding factors, directly undermining the central empirical result.
- [Abstract] Abstract (spatial join description): The integration of terminal telemetry with weather observations via 'spatial join techniques' does not report the native resolution or source of the weather data, the matching tolerance, or any sensitivity analysis for misclassification (e.g., near event boundaries or when weather grids exceed GPS precision). This is load-bearing for attributing KPI changes to weather rather than other factors and for the 55% degradation figure.
minor comments (1)
- [Abstract] The abstract states 'more than 55% affected terminals' but does not define the baseline for 'affected' or the exact degradation threshold used for KPIs.

Referee: [Abstract] Abstract: The headline claim that 'more than 55% affected terminals experienced substantial degradation' during thunderstorms/heavy rain or snow supplies no statistical methods, error bars, sample selection criteria, or validation steps. This prevents assessment of whether the fraction is robust or sensitive to confounding factors, directly undermining the central empirical result.
Authors: We agree that the abstract, as a concise summary, should provide more context for the central 55% claim to allow readers to assess its robustness. The figure derives from a direct enumeration of terminals meeting explicit degradation criteria (latency increase exceeding 50% or drop rate above 10%) during time-aligned severe weather periods, using the full set of terminals with overlapping weather observations as the sample. We will revise the abstract to briefly state the sample selection and degradation definition, and we will add error bars or bootstrap-derived confidence intervals to the corresponding results in the main text along with a short description of the correlation procedure. This addresses the concern about sensitivity to confounding factors. revision: yes

Authors: We acknowledge that the abstract omits key technical parameters of the spatial integration step. We will expand the abstract to specify the weather data source and native resolution, the spatial matching tolerance applied, and the time-alignment window. In addition, we will add a methods subsection (or appendix) that includes sensitivity checks for boundary effects and grid-precision mismatches. These additions will clarify the attribution of KPI changes to weather and support the robustness of the reported degradation fraction. revision: yes
Circularity Check
No circularity: purely observational correlation study with no derivation chain
full rationale
The paper reports empirical correlations between minute-level Starlink telemetry (1,292 terminals, 870k terminal-hours) and classified weather events via spatial joins and time alignment. No equations, models, predictions, or first-principles derivations are present that could reduce to inputs by construction. The >55% degradation statistic is a direct count from the joined dataset; the spatial-join accuracy is an unverified assumption but does not constitute circularity under the defined patterns. The work is self-contained as an observational analysis.
