To investigate the regional frequency more reasonably, the WRB is clustered into four homogenous subregions via the K -means method and some subjective adjustments. We also find that the dry risk in subregion 2 and subregion 4 might be higher than that in subregion 1. The relationship between ENSO events and extreme dry spell events in the rainy season with cross wavelet analysis method proves that ENSO events play a critical role in triggering extreme dry events during rainy season in the WRB. The Fifth Intergovernmental Panel on Climate Change IPCC report confirms a clear tendency of the probable occurrence of more extreme events in many regions around the world [ 1 ]. Global warming can possibly intensify the hydrological cycle and thus can result in changes in the precipitation amount, frequency, magnitude, and intensity [ 2 , 3 ]. Therefore, studying the changing patterns of precipitation is of great importance for the evaluation of hydrological and meteorological consequences, for example, drought and flooding events, associated with global warming.

Regional frequency analysis of daily rainfall extremes using L-moments approach. Box , Islamic Republic of Iran Corresponding author: e-mail: hmalekinezhad yahoo. Received October 2, ; accepted September 2, Daily extreme precipitation values are among environmental events with the most disastrous consequences for human society. Information on the magnitudes and frequencies of extreme precipitations is essential for sustainable water resources management, planning for weather-related emergencies, and design of hydraulic structures. In the present study, regional frequency analysis of maximum daily rainfalls was investigated for Golestan province located in the northeastern Iran. This study aimed to find appropriate regional frequency distributions for maximum daily rainfalls and predict the return values of extreme rainfall events design rainfall depths for the future.

Regional flood frequency analysis RFFA remains an area of active research around the world. Obtaining reliable RFFA estimates is critical for many hydrological and environmental studies. MDS is used to form regions in catchment data space using the site characteristics and geographical distance from gauged sites. Then SVR models are applied to identify the functional relationships between flood quantiles and the catchment characteristics variables in MDS space, in particular SVR is used to capture the complexity and nonlinearity in flood generation processes that may not be easily captured in loglinear models. The leave-one-out validation procedure is used to evaluate the performance of the proposed models.

Regional Frequency Analysis of Extreme Dry Spells during Rainy Season in the Wei River Basin, China

Сняв трубку, набрал номер справочной службы и через тридцать секунд получил номер главного офиса больницы. В какой бы стране вы ни находились, во всех учреждениях действует одно и то же правило: никто долго не выдерживает звонка телефонного аппарата. Не важно, сколько посетителей стоят в очереди, - секретарь всегда бросит все дела и поспешит поднять трубку. Беккер отбил шестизначный номер.

 Панк кивнул. - Tenia el anillo. Он получил кольцо.

Еще только начинало светать, но движение уже было довольно оживленным: молодые жители Севильи возвращались после ночных пляжных развлечений. Резко просигналив, пронесся мимо мини-автобус, до отказа забитый подростками. Мотоцикл Беккера показался рядом с ним детской игрушкой, выехавшей на автостраду.

Это можно примерно перевести как… - Кто будет охранять охранников! - закончила за него Сьюзан. Беккера поразила ее реакция. - Сьюзан, не знал, что ты… - Это из сатир Ювенала! - воскликнула .

 Сотню баксов. Беккер нахмурился. - У меня только песеты. - Какая разница. Давай сотню песет.

Выхода. Судьба в это утро не была благосклонна к Беккеру. Выбегая из собора в маленький дворик, он зацепился пиджаком за дверь, и плотная ткань резко заставила его остановиться, не сразу разорвавшись. Он потерял равновесие, шатаясь, выскочил на слепящее солнце и прямо перед собой увидел лестницу.

Сьюзан нахмурилась. - Я подумала, что АНБ его ликвидировало.

Contributions are welcomed on original research leading to the characterization and understanding of air-sea interactions as they relate to meteorological phenomena and their influence on climate.
