“…These findings are consistent with the general trends revealed in the National Climate Assessment Report 2014 [7]. A strong positive relationship between the total column water vapor and the daily precipitation intensity found over the southwestern United States (Regions 5 and 6) is also supported by the findings in other parts of the world including Europe and northern Eurasia using historical observational records, and at a global scale using reanalysis products [3][4][5][6].…”

“…Winter season precipitation frequency is the number of days where precipitation exceeds 0.1 mm within each winter season, a metric used as the standard for precipitation events in many studies [6,32,33]. The seasonal total is the sum of the daily precipitation values that occurred for all three months of the season.…”

“…The seasonal total is the sum of the daily precipitation values that occurred for all three months of the season. Mean daily intensity is the seasonal total divided by the seasonal frequency for each year, which results in millimeters per day [6,12,13]. The seasonal mean air temperature is the seasonal average of mean daily temperature, and the seasonal total column water vapor is the seasonal average of the daily total column water vapor, both averaged from two values of ascending and descending passes.…”

“…Studies have suggested that precipitation extremes and daily precipitation intensity have been increasing in general, despite decreases in precipitation total and frequency of precipitation events in some places [3][4][5][6]. Studies have also suggested that increasing precipitation intensity and extremes are associated with increased surface air temperature and atmospheric water vapor [5,6].…”

Abstract:The western United States is known for its water shortages due to large seasonal and inter-annual variability of precipitation as well as increasing demand. Climate change will impact the availability of water in the western United States through the modification of precipitation characteristics. Satellite data presents the opportunity to study these changes at a fine, continuous spatial resolution-particularly in places where no traditional ground observations exist. Utilizing the Tropical Rainfall Measuring Mission (TRMM) 3B42 version 7 precipitation data, this study examines the spatio-temporal changes in precipitation characteristics over the western United States between 1998 and 2015, and their connections with the atmospheric total column water vapor and the El Niño Southern Oscillation during the winter season. The results show that precipitation frequency in the western United States has been decreasing in general, precipitation totals and mean daily intensity are increasing in northwestern United States, but decreasing in the southwest United States during the 18 years of the study time period. Additionally, results show a strong relationship between total column water vapor and the precipitation characteristics, specifically in the southwestern United States.

“…This phenomenon of decreases in the sea ice extent may be explained as a part of a positive ice-albedo feedback mechanism in which the extent of ice and snow coverage decreases in response to a decrease in surface albedo, which in turn promotes further solar heating of a water body [33]. Furthermore, the melting of Arctic sea ice leads to an increase in the water vapor content in the atmosphere over the Arctic region, which in turn affects changes in the amount, frequency and intensity of precipitation in the region [34]. Our results also showed increasing positive trends in both precipitation amount and air temperature (Figures 2a and 3b).…”

Abstract:The objectives were (i) to evaluate the relationship between recent climate change and extreme hydrological events and (ii) to characterize the behavior of hydrological events along the Alazeya River. The warming rate of air temperature observed at the meteorological station in Chersky was 0.0472 • C·year −1 , and an extraordinary increase in air temperatures was observed in 2007. However, data from meteorological stations are somewhat limited in sparsely populated regions. Therefore, this study employed historical remote sensing data for supplementary information. The time-series analysis of the area-averaged Global Precipitation Climatology Project (GPCP) precipitation showed a positive trend because warming leads to an increase in the water vapor content in the atmosphere. In particular, heavy precipitation of 459 ± 113 mm was observed in 2006. On the other hand, the second-highest summer National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution radiometer (AVHRR) brightness temperature (BT) was observed in 2007 when the highest air temperature was observed in Chersky, and the anomaly from normal revealed that the summer AVHRR BTs showed mostly positive values. Conversely, riverbank, lakeshore and seashore areas were much cooler due to the formation, expansion and drainage of lakes and/or the increase in water level by heavy precipitation and melting of frozen ground. The large lake drainage resulted in a flood. Although the flooding was triggered by the thermal erosion along the riverbanks and lakeshores-itself induced by the heat wave in 2007-the increase in soil water content due to the heavy precipitation in 2006 appeared to contribute the magnitude of flood. The flood was characterized by the low streamflow velocity because the Kolyma Lowlands had a very gentle gradient. Therefore, the flood continued for a long time over large areas. Information based on remote sensing data gave basic insights for understanding the mechanism and behavior of climate-induced extreme hydrologic events.

Intensified impact of North Atlantic Oscillation in May on subsequent July Asian inland plateau precipitation since the late 1970s

The relationship between the North Atlantic Oscillation (NAO) in May and precipitation in the Asian inland plateau (AIP) in following July has experienced a significant enhancement since the late 1970s. This study investigates the factors for this inter‐decadal change of the NAO–AIP precipitation connection. Before the late 1970s, geopotential height anomalies related to the May NAO exhibited a dipole pattern confined to the North Atlantic from May to June and decayed in July. As a result, the impact of the May NAO on the AIP precipitation in July is weak. In contrast, after the late 1970s, geopotential height anomalies associated with the May NAO persisted into July. The analysis in this study finds that the May NAO influences July AIP precipitation via modulating the Polar–Eurasia teleconnection (POL). After (before) the late 1970s, the connection between the May NAO and the POL was strong (weak), explaining the inter‐decadal change in the May NAO–July AIP precipitation relationship. Further analysis suggests that the strengthening of the relationship between the May NAO pattern and the July POL after the late 1970s may be attributed to the inter‐decadal contraction of the Northern Hemisphere circumpolar vortex.
