التحديات في الانتقال من الشبكات التقليدية إلى الشبكات الأوتوماتية لرصد الأحوال الجوية من أجل السجلات المناخية طويلة الأجل
نُشرت بالفعل (WMO, 2007) توجيهات لإدارة التغيرات في برامج رصد المناخ، مع مجموعة ممارسات موصى بها يمكن بواسطتها إدارة هذه التغيرات. وسينصب التركيز في هذه المذكرة التوجيهية على محطات الأرصاد الجوية الأوتوماتية (AWSs) التي يرجح أن تشكل جزءاً من السجلات المناخية طويلة الأمد. وستكون هذه السجلات عادة مملوكة للمرافق الوطنية للأرصاد الجوية والهيدرولوجيا (NMHSs) أو للوكالات المنتسبة لها، أو لأطراف أخرى أحياناً (من قبيل هيئات الطيران أو الزراعة أو النقل البري) في إطار المعايير التي تقرها المرافق الوطنية (NMHSs). وتثبت التجربة أن المحطات (AWSs) الخاصة يمكن أن تكون مفيدة لبعض الأغراض المناخية (مثل توفير م ...

长期气候记录从常规气象观测网向自动气象观 测网过渡中的挑战
世界气象组织 (WMO) - WMO, 2017WMO已经发布了管理气候观测计划变化的指导原则,其中有一套可以管理这种变化的建议做法(WMO,2007)。本指南将侧重于那些可能构成长期气候记录一部分的AWS。这些AWS 通常由NMHS 或相关机构所有,或有时由第三方(如航空、农业或公路运输机构)根据NMHS认可的标准拥有。经验表明,私人AWS对某些气候目的是有用的(如提供个别局地尺度的极端事件信息),但很少能达到所需的记录长度、准确性或敞度标准,或场地和仪器的长期稳定性,不可能对十年或更长的时间尺度的监测有很大价值。

Challenges in the Transition from Conventional to Automatic Meteorological Observing Networks for Long-term Climate Records
Guidelines for managing changes in climate observation programmes, with a set of recommended practices by which such changes can be managed, have already been published (WMO, 2007). This guidance note will focus on those AWSs likely to form part of long-term climate records. These will normally be owned by NMHSs or associated agencies, or sometimes by third parties (such as aviation, agriculture or road transport agencies) under standards endorsed by the NMHSs. Experience shows that private AWSs can be useful for some climate purposes (such as providing information on individual local-scale ex ...

Reservoir Pool Elevation: Considerations for Long-term Asset Management and Planning
Long-term management of critical water resources infrastructure needs to incorporate projected changes to environmental conditions. Reservoirs form the heart of water resource assets. Long-range plans for the repair, replacement, maintenance and renovation of these facilities depend on accurate projections of reservoir pool elevations. Environmental conditions, in turn, dictate the magnitude and timing of inflows and outflows from reservoirs, and thus the resulting water surface elevation. This lesson explores the factors that affect reservoir pool elevation and the considerations and challeng ...

WMO Guidelines on the Calculation of Climate Normals
The focus of this document is on observations at surface meteorological observing stations. However, many of the principles will also be valid for other forms of observations, including upper-air observations and datasets based on mobile or remotely sensed platforms (for example, satellites, radar or drifting buoys). In particular, as many key remotely sensed datasets begin in the 1970s, it is recommended that, where feasible, the current climatological standard normal period (1981–2010 at the time of writing) be used for these datasets to allow comparison among different data forms on a consi ...

Analysis inter decadal of climate variability facing projections of the CMIP5 models and its involvement in the agricultural production of Venezuela
Agriculture is the largest employer in the world and is probably the most dependent on the climate of all human activities. In recent years there have been events that have put in evidence the vulnerability of global food security to major meteorological phenomena, both in global agricultural markets and the world economy. The food price crisis and the subsequent economic crisis reduced the purchasing power of large segments of the population in many developing countries, which seriously reduced their access to food and thus undermined their food security. During the years 2009 and 2010 in Ven ...

Climate change effect on wheat production over Ethiopia by model simulation and prediction
Climate is one of the key factors that affect agriculture. Climate change and climate variability have been observed, typically shown as global warming due to the increased greenhouse gases. The change in climate is even predicted to be rapped and sharp in recent future and the impacts of extreme climate condition associated with climate change will be high on agriculture. Studying the impacts of climate change, especially the effects of temperature and precipitation on agriculture, is important for food safety, agricultural management, and sustainable development.

The global community is rapidly putting in place measures to protect societies from adverse socioeconomic and environmental impacts caused by extreme weather-, climate- and water-related events, and also to take maximum advantage of any positive benefits of these changes that may exist. However, many projects are being undertaken in isolation, in the absence of mechanisms for alignment of the diverse efforts being made at project level, and without conforming to relevant international standards. This can result in duplication of efforts, which may prove unsustainable or ineffective in the long ...

WMO Statement on the state of the global climate in 2016
This latest report confirms that 2016 was the warmest year on record: a remarkable 1.1 °C above the pre-industrial period, which is 0.06 °C above the previous record set in 2015. This increase in global temperature is consistent with other changes in the climate system. Globally averaged sea-surface temperatures were also the warmest on record; global sea levels continued to rise; and Arctic sea-ice extent was well below average for most of the year.
