previously been linked to an earlier finish to the melt season (i.e., depletion of frozen water stores) ( Hodgkins et al. 2005 ). Consequently, May and June experience reduced meltwater input to river flow. Huntington et al. (2003) show an analogous temporal dynamic for river–ice thickness variation in Maine. This hypothesis is further supported by an increased land–sea temperature contrast in May and June low flow composites: these show higher air temperatures over land rather than a cooler sea

Wernli 2011 ). These depend not only on the synoptic situation but also on processes not explicitly considered in the NWP model, such as condensational processes on subgrid scale; the phase transitions of water between vapor, cloud, and ice; and vertical convective transports of heat and moisture on subgrid scale ( Damrath et al. 2000 ; Shrestha et al. 2013 ). For these reasons, NWP QPF is still relatively unsatisfactory, especially for small-scale and short-term high-precipitation events ( Cuo and

convective precipitation are critical to improving models and, thus, improving predictions of the NAMS. The Sierra Madre Occidental (SMO) dominates the regional geography of the NAMS, extending from sea level to over 3000 m in elevation in several locations near the west coast of Mexico, which contains deep canyon systems, steep slopes, and high plateaus ( Fig. 1 ) that greatly impact low- to midlevel atmospheric flow features in the region ( Johnson et al. 2007 ). The SMO produces diurnally modulated

1. Introduction The topography of the western United States poses a significant challenge in creating physically realistic and spatially accurate estimates of precipitation using remote sensing techniques. Simply stated, complex terrain serves as a hostile observing environment for radars of any size and wavelength. This is further compounded by the presence of complex microphysical processes during the cool season as a result of air–sea interactions within coastal regions as well as the

River, we monitored a large rainfall event during July 1999. This precipitation event generated a runoff response that was approximately 3 times larger than any previously measured discharge during the 1993–2001 period. What physical conditions need to prevail that would result in significant rainfall on the North Slope of Alaska? Low air temperature, mountainous topography, and an extensive ice cover over the Arctic Ocean all combine to reduce the amount of precipitable water in the atmosphere over

high emissivity of the surface and its large variability mask atmospheric emission signatures and make precipitation nearly indistinguishable from the background. To overcome this problem, passive microwave retrievals over land focus on ice-scattering signals, which are less well related to precipitation but more easily detected over a warm surface background. This limited information content weakens the linkage between satellite measurements and the a priori database and exposes the algorithm to

earth. The region is one of the most glaciated regions of the Nepal Himalayas. The extreme terrain, hostile climate, and poor accessibility are major impediments to snow measurements. Many studies have been conducted in the Nepal Himalayas regarding snow and ice melt modeling (e.g., Fukushima et al. 1991 ; Braun et al. 1993 ; Rana et al. 1997 ; Sharma et al. 2000 ; Chalise et al. 2003 ; Kayastha et al. 2005 ; Rees and Collins 2006 ; Konz et al. 2007 ; Shrestha et al. 2010a ; Alford and

1. Introduction Precipitation in the Arctic affects the ocean and terrestrial freshwater budgets, the surface albedo and energy budget, as well as the mass balance of ice sheets, glaciers, and sea ice ( AMAP 2017 ). During recent decades, tropospheric water vapor ( Serreze et al. 2012 ) and precipitation ( Hartmann et al. 2013 ; Willett et al. 2013 ; Hanssen-Bauer et al. 2019 ) have generally increased in the Arctic. The increased precipitation is linked to the general warming, partly driven
