Snowfall Characterization by Field Observation and Atmospheric Sounding
The snowfall rate is related to microphysical and dynamical processes in weather systems and is further specified by choice of measurement time, related to the statistics of individual falling ice crystals. A snowflake is definable as a single ice crystal having long range order in the crystal …

Trend Reversal in Lake Michigan Contribution to Snowfall
… impact the region’s climate is by augmenting snowfall in downwind locations during autumn and winter months. Among many negative consequences, this surplus of snow can cause substantial property damage to homes and can escalate the number of traffic accident-related injuries and fatalities. …

A statistical approach to predicting snowfall using the SPF
A snowfall potential probability density function is introduced that uses an alternate method of statistical analysis in predicting snowfall by using concepts of normal probability distributions. The snowfall potential function (hereby referred to as the SPF) assumes certain identifiers are …

A physical model to estimate snowfall over land using microwave measurements
… significant. However, the scattering effect of snowfall in the atmosphere at those higher frequencies is also impacted by water vapor and supercooled water in the upper atmosphere.The Discrete Dipole Approximation (DDA) method was employed to generate the single scattering parameters for …

Snowfall Interception and Ablation in Needleleaf Canopies: Observations and Model Development
… vegetation cover have the potential to alter how snowfall is intercepted and subsequently partitioned between sublimation to the atmosphere or unloading, melt, and drip to the ground; however, the understanding required to investigate potential changes to water resources and energy exchanges is …

Influence of summer snowfall on discharge emanating from the Gangotri glacier
… this investigation was to determine how summer snowfall events between 2001 & 2004 influenced runoff flowing from Gangotri glacier, located in the Garhwal region of the Himalayas. This was achieved by collating air temperature, precipitation and discharge data for the study area. Data were used …

A study of lightning flashes attending periods of banded heavy snowfall
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lighting[sic] flashes associated with 24 banded thundersnow events were analyzed to document their polarity, signal strength, and multiplicity. Radar reflectivity values were recorded at each lighting flash, as well as the …

Assessing fall velocity-maximum dimension relationships and particle size distributions for snowfall
Snowfall is an atmospheric phenomenon that can cause significant impacts to many aspects of daily life in Missouri. Further, no two snowfall events are exactly the same, as even small differences in environmental characteristics can result in differing snow crystal types dominating the event, which …

A comparison of microphysical properties in lake-effect and synoptic snowfall near Buffalo, NY
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2026-08-01

Effects of Air Temperature and Lake Ice on Snowfall on the South Shore of Lake Superior
… on the south shore of the lake. Rainfall and snowfall amounts from December to May were regressed on percent ice coverage and average monthly temperatures from 1972-2002. Ice coverage and average monthly temperature had a negative relationship with snowfall and rainfall.

Evaluations of microphysical parameterizations in retrieval algorithms for snowfall particle size distributions from dual frequency radar measurements
… have the potential for novel retrievals of snowfall precipitation from space. These retrievals are dependent on assumptions that relate the maximum measured dimension of a snowflake to its mass and radar cross-section, as well as assumptions to constrain the shapes of snowflake particle size …

Evaluation of triple-frequency radar retrieval of snowfall properties using coincident airborne in-situ observations during olympex
Particle scattering models have shown that aggregates and spherical particles occupy distinct regions of the Ku-Ka-W-band Dual-Frequency Ratio (DFR) plane. Furthermore, ground-based observations suggest that particle bulk density and characteristic size can be retrieved from the DFR plane. This is …

Snowstorms in Upstate New York: synoptics, spatial modeling and temporal variability
… examine their relative contribution to seasonal snowfall totals. Although lake-effect snowstorms are the dominant snowfall contributor for most of Central New York, their contributions vary considerably across the region. These storms contribute approximately 50% of the seasonal snowfall totals …

A new snowfall detection algorithm for high latitude regions based on a combination of active and passive sensors
… retrieval over high latitudes, particularly snowfall retrieval over ice and snow, using satellite-based passive microwave spectrometers, is currently an unsolved problem. The challenge results from the large variability of microwave emissivity spectra for snow and ice surfaces, which can …

Climate Change in Buffalo, NY
… are that average winter temperatures and snowfall should be increasing, Lake Erie should be freezing at a later date, and Lake Erie’s ice cover should affect snowfall amounts. The warmer temperatures would lead to Lake Erie’s surface water temperature being higher, resulting in less ice …

An East Coast Winter Storm Precipitation Climatology
… This climatology consists of the percentage of snowfall and precipitation from ECWS, on average per snow year. The exclusion of non-ECWS snowfall and precipitation during ECWS events is accomplished by utilizing a precipitation gradient line, a pressure gradient line, and the presence of a …

Improving active remote sensing retrievals of snowfall at microwave wavelengths: an emphasis on the global precipitation measurement mission’s dual-frequency precipitation radar
Even though snowfall at the surface is often constrained to higher latitudes or altitudes, the contribution of solid-phase hydrometeors to the hydrologic cycle is not trivial and can be related to more than 50% of all surface rain events. Furthermore, the quantification of snow and ice in the …

Multi-Satellite Remote Sensing of Land-Atmosphere Interactions: Advanced Data-Driven Methodologies for Passive Microwave Retrievals of Flood and Precipitation
… and (2) the precipitation phase (rainfall or snowfall). Remote sensing of snowfall is still very new and challenging despite that snowfall accounts for the majority of total precipitation events over mid- to high latitudes and its spatial distribution conditions the snowpack dynamics and …
