Abstract California experienced a historic run of nine consecutive landfalling atmospheric rivers (ARs) in three weeks’ time during winter 2022/23. Following years drought from 2020 to 2022, intense ARs across December 2022–January 2023 were responsible for bringing reservoirs back historical averages and producing damaging floods debris flows. In recent years, the Center Western Weather Water Extremes collaborating institutions have developed routinely provided end users peer-reviewed...
Drought is one of the most prominent natural threats to grassland productivity, although magnitude this threat uncertain due different drought-levels. However, drought-productivity dynamics has not yet received much attention. It necessary establish method evaluate quantitatively effect drought-levels on productivity. To better understand impact productivity dynamics, an assessment assess quantitative effects was proposed based-on long-term observation data, standardized precipitation index...
Abstract This study demonstrates a possible impact of the quasi‐biennial oscillation (QBO) on Madden‐Julian Oscillation (MJO)‐related North Pacific storm track (NPST) change during October–March for period 1979–2016. The NPST shows significant intraseasonal changes in response to MJO. In general, when MJO convection is located over Indian Ocean (western central Pacific), tends shift poleward (southward). MJO‐related has larger amplitude easterly phase QBO (EQBO) than its westerly (WQBO)....
Abstract Storm tracks, defined as the preferred regions of extratropical synoptic‐scale disturbances, have remarkable impacts on global weather and climate systems. Causes interannual storm track variation been investigated mostly from a troposphere perspective. As shown in this study, Northern Hemisphere winter tracks are significantly modulated by tropical stratosphere through quasi‐biennial oscillation (QBO). The North Pacific shifts poleward during easterly QBO winters associated with...
Flood disasters are one of the most serious meteorological in China. With rapid development information technology, individual monitoring tools could not meet need for flood disaster monitoring. Therefore, a new integrated air-space-ground method, based on combined satellite remote sensing, unmanned aerial vehicle sensing and field measurement has been proposed to monitor assess caused by dam failure Poyang County, Jiangxi Province. In this paper, an investigation system, general flooded...
Abstract Extreme weather and climate events can have substantial impacts on society the environment. Compound extremes (two or more extreme occurring simultaneously successively) may exert even larger than individual events. Here we examine physical drivers behind variability in hydrometeorological (precipitation temperature) compound subseasonal-to-seasonal timescales. Observational evidence presented here through composite analysis indicates that frequency is linked to Madden-Julian...
Abstract The Madden–Julian oscillation (MJO) is a unique type of organized tropical convection varying primarily on subseasonal time scales and recognized as an important source predictability for midlatitude weather phenomena. This study provides observational evidence MJO impacts precipitation extreme intensity, frequency, duration over the western United States. results suggest robust increase in extremes, especially relative to climatological conditions most States when its Pacific...
Abstract In an assessment of 29 global climate models (GCMs), Part I this study identified biases in boreal winter MJO teleconnections anomalous 500-hPa geopotential height over the Pacific–North America (PNA) region that are common to many models: eastward shift, a longer persistence, and larger amplitude. II, we explore relationships teleconnection metrics developed with several existing newly basic state (the mean subtropical westerly jet) metrics. The diagnostics indicate is generally...

Abstract This paper examines the empirical relationship between Madden–Julian oscillation (MJO), quasi‐biennial (QBO), and atmospheric river (AR) activity precipitation in California on subseasonal time scales. We introduce an experimental forecast tool that uses observed anomaly patterns during a 38 yr period to predict probability of above‐ below‐normal AR at lead times 1–6 weeks based phase amplitude MJO QBO. The hindcast prediction skill probabilistic forecasts is evaluated for Northern,...
Abstract. The MJO-Teleconnections diagnostics package is an open-source Python software that provides process-level evaluation of predicted by subseasonal-to-seasonal (S2S) forecast systems. in-depth both tropospheric and stratospheric pathways defining the atmospheric teleconnections from tropics to extratropics on S2S times scale. analyses include comparison a model with default verification data set or user-provided data. consists user-friendly graphic user interface (GUI), which allows...
Abstract We propose a set of MJO teleconnection diagnostics that enables an objective evaluation model simulations, fair model-to-model comparison, and consistent tracking improvement. Various skill metrics are derived from including five performance-based characterize the pattern, amplitude, east–west position, persistence, consistency teleconnections additional two process-oriented designed to location intensity anomalous Rossby wave source (RWS). The proposed used compare characteristics...
Abstract Future changes in boreal winter MJO teleconnections over the Pacific–North America (PNA) region are examined 15 Coupled Model Intercomparison Project phase 6 models (CMIP6s) under SSP585 (i.e., Shared Socioeconomic Pathway 5 following approximately representative concentration pathway RCP8.5) scenarios. The most robust and significant change is an eastward extension (∼4° for multimodel mean) of North Pacific. Other projected include a northward extension, more consistent patterns...
One-time application of blended controlled-release nitrogen fertilizer (CRN) has the potential to solve difficulty top-dressing in cultivation rice and reduce cost CRN application. However, its effects on dry matter (N) accumulation translocation, yield N-use efficiency (NUE) remain uncertain.

There an established lag impact ecosystems events, which may have additional effects subsequent events. Meanwhile, due change interference, influence over past 50 years not simply equal algebraic sum all historical In Inner Mongolia grassland, precipitation deficit plays a leading role in causing drought. Therefore, taking into consideration impacts effect and change, paper, we net...
