This study presents the climatic trend of the North Atlantic wind energy using cross-calibrated, multiplatform CCMP wind data for the period — Results show the following. The increasing trend in the mid-high latitudes is stronger than that in the low latitudes, and the trend is stronger in the west than in the east.

Other data that support the findings of this study are available from the indicated sources or from the corresponding author upon reasonable request.

Space-borne satellites provide extensive coverage of measuring sea surface wind field and wave heights on a global scale. The present study provides a comprehensive assessment of distribution of extreme wind and wave fields over the Indian Ocean IO utilizing satellite-based scatterometer and altimeter datasets. A decadal variability was observed in the inter-annual spatial distribution of the 90th and 95th percentile winds for the study region. Interestingly, the study reveals a declining trend in the dispersion of higher waves 90th, 95th, and 99th percentiles in the entire IO except the South China Sea. Further, onwards there is an increasing trend in the annual distribution of extreme winds and waves for the Extra-tropical South Indian Ocean having implications on the generation of swell wave fields.

Multiplatform evaluation of global trends in wind speed and wave height.

A Publisher Correction to this article was published on 19 June Differences between altimeter and buoy data as a function of time are investigated for long-term stability. A cross validation between altimeters is also carried out in order to check the stability and consistency of the calibrations developed.

Wind and waves are key components of the climate system as they drive air-sea interactions and influence weather systems and atmospheric circulation. In marine environments, understanding surface wind and wave fields and their evolution over time is important for conducting safe and efficient human activities, such as navigation and engineering. The long-term trends in WS and SWH in the China Seas are analyzed over the past 24 years to provide a reference point from which to assess future climate change and offshore wind and wave energy resource development in the region.

Long-term changes in ocean surface wind speed and wave height have received increasing attention as climate change impacts have become evident Young et al. Changes in surface wind speed and wave height may dramatically affect coastal communities Ranasinghe , as well as offshore operations Bitner-Gregersen et al. Trend analyses of global ocean surface wind speed and wave height rely on observational and modeled datasets. Long time series of surface wind speed and wave height observations originate from shipboard measurements that date back to , the year marking the beginning of an internationally organized system for recording shipboard meteorological observations Maury ; Cardone et al. Studies of VOS marine wind speed have shown that these datasets are affected by changes in measuring techniques. This is especially relevant in the first part of the century, where the absence of universal standards for estimated winds formalization of sea-state equivalent Beaufort scale took place in ; Thomas et al.

Recent trends in wind-wave climate for the Indian Ocean

The model performance is satisfactory. Results showed that trends greater than 0. During winter, strong positive trends 0. Significant trends greater than 0. In summer, significant increasing trends 0. During autumn, strong positive trends between 0. Furthermore, temporal trend analysis showed that the extreme SWH exhibits a significant increasing trend of 0.

Ответ, уже из могилы, дал Чатрукьян. Стратмор отключил программу Сквозь строй.

Trends in significant wave height and surface wind speed in the China Seas between 1988 and 2011

Вцепившись руками в спинку стула, Бринкерхофф в ужасе смотрел на экраны. - Чед? - услышал он голос у себя за спиной. Обернувшись, Бринкерхофф начал всматриваться в темноту. Мидж как ни чем не бывало стояла в приемной возле двойной двери директорского кабинета и протягивала к нему руку ладонью вверх.

Может быть, он что-нибудь поджег. Она посмотрела на вентиляционный люк и принюхалась. Но запах шел не оттуда, его источник находился где-то поблизости. Сьюзан посмотрела на решетчатую дверь, ведущую в кухню, и в тот же миг поняла, что означает этот запах. Запах одеколона и пота.

Не открыв своего алгоритма, он доказал АНБ, что тот не поддается дешифровке. Стратмор протянул Сьюзан газетную вырезку. Это был перевод рекламного сообщения Никкей симбун, японского аналога Уолл-стрит джорнал, о том, что японский программист Энсей Танкадо открыл математическую формулу, с помощью которой можно создавать не поддающиеся взлому шифры. Формула называется Цифровая крепость, говорилось в заметке, и доступна для ознакомления в Интернете. Программист намеревался выставить ее на аукционе и отдать тому, кто больше всех заплатит.

Recent Decadal Trend in the North Atlantic Wind Energy Resources

 Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает. - Убедительно.

 - Почему вы считаете, будто Танкадо не знал, что на него совершено покушение. Смит откашлялся. - Халохот ликвидировал его с помощью НТП - непроникающей травматической пули. Это резиновая капсула, которая при попадании растворяется.

Стратмор нахмурился: - Танкадо намерен назвать победителя аукциона завтра в полдень. Сьюзан почувствовала, что у нее сводит желудок. - А что. - Он говорит, что вручит победителю ключ. - Ключ.

We find a general global trend of increasing values of wind speed and, to a lesser degree, wave height, over this period. The rate of increase is.

The determination of extreme-value estimates of environmental parameters such as wind speed and wave height is a common requirement for many coastal and offshore applications.
