Abstract A climatological analysis was conducted of the environmental and atmospheric conditions that occurred during 125 identified lake-effect (LE) precipitation events in the New York State Finger Lakes region for the 11 winters (October–March) from 1995/96 through 2005/06. The results complement findings from an earlier study reporting on the frequency and temporal characteristics of Finger Lakes LE events that occurred as 1) isolated precipitation bands over and downwind of a lake (NYSFL events), 2) an enhancement of LE precipitation originating from Lake Ontario (LOenh events), 3) an LE precipitation band embedded within widespread synoptic precipitation (SYNOP events), or 4) a transition from one type to another. In comparison with SYNOP and LOenh events, NYSFL events developed with the 1) coldest temperatures, 2) largest lake–air temperature differences, 3) weakest wind speeds, 4) highest sea level pressure, and 5) lowest height of the stable-layer base. Several significant differences in conditions were found when only one or both of Cayuga and Seneca Lakes, the largest Finger Lakes, had LE precipitation as compared with when the smaller Finger Lakes also produced LE precipitation. In addition, transitional events containing an NYSFL time period occurred in association with significantly colder and drier air masses, larger lake–air temperature differences, and a less stable and shallower boundary layer in comparison with those associated with solitary NYSFL events.

Abstract This study presents a climatological analysis of the frequency and characteristics of lake-effect precipitation events that were initiated or enhanced by lakes within the New York State (NYS) Finger Lakes region for the 11 winters (October–March) from 1995/96 through 2005/06. Weather Surveillance Radar-1988 Doppler (WSR-88D) data from Binghamton, New York, were used to identify 125 lake-effect events. Events occurred as 1) a well-defined, isolated precipitation band over and downwind of a lake, 2) an enhancement of mesoscale lake-effect precipitation originating from Lake Ontario and extending southward over an individual Finger Lake, 3) a quasi-stationary mesoscale precipitation band positioned over a lake embedded within extensive regional precipitation from a synoptic weather system, or 4) a transition from one type to another. Results show that lake-effect precipitation routinely develops over lakes that are considerably smaller than lakes previously discussed as being associated with lake-effect precipitation, such as the Great Lakes. Lake-effect events occurred during each month (October–March) across the 11 winters studied and were identified in association with each of the six easternmost Finger Lakes examined in this study. The frequency of NYS Finger Lakes lake-effect events determined in the current investigation paired with subsequent analyses of the environmental conditions leading to these events will allow for 1) comparative analyses of necessary conditions for lake-effect development across a range of lake sizes (e.g., NYS Finger Lakes, Lake Champlain, Great Salt Lake, and Great Lakes) and 2) an informative examination of the connection between mesoscale processes and climate variability.

Lake Effect

AbstractLake-effect storms (LES) produce substantial snowfall in the vicinity of the downwind shores of the Great Lakes. These storms may take many forms; one type of LES event, lake to lake (L2L), occurs when LES clouds/snowbands develop over an upstream lake (e.g., Lake Huron), extend across an intervening landmass, and continue over a downstream lake (e.g., Lake Ontario). The current study examined LES snowfall in the vicinity of Lake Ontario and the atmospheric conditions during Lake Huron-to-Lake Ontario L2L days as compared with LES days on which an L2L connection was not present [i.e., only Lake Ontario (OLO)] for the cold seasons (October–March) from 2003/04 through 2013/14. Analyses of snowfall demonstrate that, on average, significantly greater LES snowfall totals occur downstream of Lake Ontario on L2L days than on OLO days. The difference in mean snowfall between L2L and OLO days approaches 200% in some areas near the Tug Hill Plateau and central New York State. Analyses of atmospheric conditions found more-favorable LES environments on L2L days relative to OLO days that included greater instability over the upwind lake, more near-surface moisture available, faster wind speeds, and larger surface heat fluxes over the upstream lake. Last, despite significant snowfalls on L2L days, their average contribution to the annual accumulated LES snowfall in the vicinity of Lake Ontario was found to be small (i.e., 25%–30%) because of the relatively infrequent occurrence of L2L days.

The chromosomal constitutions of three species in the jenningsi-group in the Adirondacks and the Finger Lakes Region in New York State are detailed. No sibling species were found in Simulium jenningsi, S. fibrinflatum, or S. luggeri in these areas. The species were found to differ by 6 fixed inversions and by 19 floating inversions. 4 of which are related to sex determination in S. jenningsi. The major chromosomal differences between the venustutm-group and the jenningsi-group are detailed. The ancestral condition for each arm was determined using ex-group and L′ analyses. A phylogenetic sequence for these three species from the ancestral condition is proposed.
