The drought of – in California imposed severe stress on the state’s water resources. USAGE-TERM is a multi-regional CGE model that represents 12 key irrigation counties in California as separate economies.

Water trading between irrigators would help California cope with by: 2. This is a comprehensive presentation of the theory and practice of time series modelling of environmental systems. A variety of time series models are explained and illustrated, including ARMA (autoregressive-moving average), nonstationary, long memory, three families of seasonal, multiple input-single output, intervention and multivariate ARMA models.

The standardized drought indices (e.g., SSI) has its own advantages over other drought indices [Van Loon, ;Mishra and Singh, ] in that: (a) it is derived using single variable (e.g. Drought is a slow‐onset, creeping natural hazard and a recurrent phenomenon in the arid and semi‐arid regions of Gujarat (India).

In Asia, the standardized precipitation index (SPI) has gained wider. Skip to Main Content. The ET-based drought assessment was compared with conventional precipitation-based analyses using the Standardized Precipitation Index (SPI) in respect of severity, areal extent, and temporal trends.

Weather‐pattern, or weather‐type, classifications are a valuable tool in many applications as they characterize the broad‐scale atmospheric circulation over a given region. This study analyses the aspects of regional UK precipitation and meteorological drought climatology with respect to a new set of objectively defined weather patterns.

Drought is an extreme climate phenomenon that happens slowly and periodically threatens the environmental and socio-economic sectors. Iraq is one of the countries in the Middle East that has been dealing with serious drought-related issues in the 21st century.

Here, we investigate meteorological drought across Iraq from to at ° spatial resolution.

In this study, the proposed MSDI is utilized to characterize the drought conditions over several Climate Divisions in California and North Carolina. The MSDI-based drought analyses are then compared with SPI and SSI.

Abstract. Drought is one of the world's primary natural hazards because of its environmental, economic, and social impacts. Therefore, monitoring and prediction for small regions, countries, or whole continents are challenging.

In this work, the meteorological droughts affecting the Miño–Limia–Sil hydrographic demarcation in the northwestern Iberian Peninsula during the period of The identification of drought-prone areas is, however, challenging due to the complex nature of drought events with their slow onset and unclear definition [15,16].Four types of drought can be identified []: (i) Meteorological drought is defined as a less-than-normal amount of precipitation for a certain region and time period [15,17,18].If the water deficit leads to a drop in soil moisture.

These are (1) a more precise determination of drought duration, (2) the usefulness in monitoring an ongoing drought and (3) the variety of ways a drought's characteristics can be described. [Software is available via ftp with no charge.

The SPI was developed to categorize rainfall as a standardized departure with respect to a rainfall probability distribution function; categories range from less than -3 (extremely dry) to more than +3 (extremely wet).

The SPI is calculated on the basis. Ignazio Giuntoli, Gabriele Villarini, Christel Prudhomme, Iman Mallakpour and David M.

1. Introduction. Tropical and subtropical land ecosystems play crucial roles in ecosystem services of food, biodiversity, land productivity, and water supply, and they dominate the global terrestrial carbon and hydrological cycle and help to mitigate human-induced climate change (Ballantyne et al., ; Beer et al., ; Jung et al., ).The biomes play diverse roles in ecosystem services.

California has a Mediterranean climate – cool, wet winters and warm, dry summers. This means that the bulk of California’s precipitation falls in the cool season months from October through April.

It is highly variable across the state with the southeast deserts receiving less than 5 inches in a year to the north coast which can get over. The authors suggest that atmospheric rivers are the cause of California's increasingly extreme, yet infrequent bouts of precipitation. Based on projections of future climate, the authors found that while overall precipitation will remain the same over the long-term for California, it will fall in less frequent but more extreme bursts.

This is essentially the probability of getting the required precipitation based on the historical record of precipitation. If the Palmer model says that a location needs a lot of precipitation to end its drought, but that amount of precipitation has rarely fallen throughout the historical record, then the probability of the drought ending there.

Within this low-order modeling framework, extreme events emerge either because of the increased amplitude of WWEs or changes in their characteristics (e.g., frequency of occurrence) (Levine et al., ), which is consistent with previous works using more complex models (Lengaigne et al.,Gebbie et al.,Kapur and Zhang,Chen.Based on Palmer drought analysis, the precipitation required to end or ameliorate drought in 12 timescales (1- to months), the percent of normal precipitation this amount is, and the probability of receiving this amount of precipitation based on the historical record; worst case scenarios and projected scenarios are included.Drought Characteristics and Propagation in the Semiarid Heihe River Basin in Northwestern China F.
