1. Introduction Explosive extratropical cyclones are defined as when the surface central pressure falls at a rate of at least 1 mb h −1 for 24 h (1 mb = 1 hPa), also called meteorological “bombs” ( Sanders and Gyakum 1980 ). Explosive cyclones, as severe weather disasters, induce heavy precipitation with devastating floods and cause great damage to human society during boreal winter, especially in the northwestern region of the Pacific and Atlantic oceans ( Sanders and Davis 1988 ; Yoshida

investigated based on the direct or remote influences of four large-scale triggers: Atmospheric circulations and patterns . For example, propagating Rossby waves originating in the west Pacific lead to upper-level enhanced anticyclones during the 1988 Great Plains drought ( Chen and Newman 1998 ), while the descending branch of the Hadley circulation is responsible for amplified subsidence and associated long-term precipitation deficits during the 2011 eastern China spring–summer drought ( Jin et al

mean temperature increase rate is generally higher than that of the ocean due to the small inertia of the continents on most lands ( Byrne and O’Gorman 2013 ). Yet, the increase in temperature shows great spatial differences on land, with the largest increase in average temperature at the mid- to high-latitude region of the Northern Hemisphere ( IPCC 2018 , 2019 ). Several studies pointed out that the increase in hot extremes can be impacted by surface dryness feedback, leading to a sharp increase

simulations EXP3, EXP4, and EXP5 were performed by modifying the albedo over the selected large area. We imposed a high land surface albedo of 0.85 in EXP3, which mimics the albedo of white sand; a low surface albedo of 0.08, which mimics the ocean albedo in EXP4; and an intermediate albedo of 0.2 in EXP5, which mimics the effect of solar panels on surface energy balance (2). To study the effects of topography, size, and geographic position of the geoengineered region on precipitation, we applied the same

SENAMHI for operational purposes in Peru for droughts and floods monitoring at the national scale, and was applied for hydrological modeling of the Andean Vilcanota River catchment ( Fernandez-Palomino et al. 2020 ), catchments draining into the Pacific Ocean ( Asurza-Véliz and Lavado-Casimiro 2020 ), and Peruvian catchments ( Llauca et al. 2021 ). As the method used to generate PISCO mainly corrects the biases of CHIRP using in situ precipitation data, the higher accuracy of precipitation estimates

surface air temperature, particularly in the tropics, has already started to emerge ( Wei et al. 2014 ). In addition, southern China frequently witnesses the persistence of extremely high temperature or heat waves during summer. Rainfall following a dry spell can be the most anticipated weather phenomenon with possibilities to bring down the air temperature. However, the cooling effect of precipitation on air temperature has not been well investigated in southern China, especially on hourly time

1. Introduction Today’s numerical weather prediction (NWP) models are, in fact, numerical Earth system weather prediction (NEWP) models (e.g., Benjamin et al. 2019 ) including internal prognostic treatment of land/vegetation, snow, ice, lakes, waves, and atmospheric composition. Representation of transfers of energy and moisture through these Earth system boundaries is an essential component of these prediction models. Lewis Richardson foresaw 100 years ago the importance of diabatic and

Spatially, the upper limit (viz., the first maximum value) of the correlation coefficient decreases from subbasins I and II in the northern (0.63) to subbasins III–V in the south (0.26). Specifically, water vapor transport from zonal westerly circulations and dry and cold airflow from the Arctic Ocean are the atmospheric moisture sources for Xinjiang. The blockage of the Karakoram and Kunlun Mountains makes it

Furthermore, the terrestrial water storage component has been isolated by reducing the gravitational effect of atmospheric mass changes from the daily gravity field ( Kvas et al. 2019 ). The ITSG-Grace2018 dataset was derived from spherical harmonic coefficients expansion up to the degree/order of 40 and released as the gridded TWSA with a spatial resolution of 1°. To restore daily TWSA signals from
