Meteorology Climate
Meteorology: Climate • Climate is the third topic in the B-Division Science Olympiad Meteorology Event. • Topics rotate annually so a middle school participant may receive a comprehensive course of instruction in meteorology during this three-year cycle. • Sequence: 1. Climate (2006) 2. Everyday Weather (2007) 3. Severe Storms (2008) Weather versus Climate Weather occurs in the troposphere from day to day and week to week and even year to year. It is the state of the atmosphere at a particular location and moment in time. http://weathereye.kgan.com/cadet/cl imate/climate_vs.html http://apollo.lsc.vsc.edu/classes/me t130/notes/chapter1/wea_clim.html Weather versus Climate Climate is the sum of weather trends over long periods of time (centuries or even thousands of years). http://calspace.ucsd.edu/virtualmuseum/ climatechange1/07_1.shtml Weather versus Climate The nature of weather and climate are determined by many of the same elements. The most important of these are: 1. Temperature. Daily extremes in temperature and average annual temperatures determine weather over the short term; temperature tendencies determine climate over the long term. 2. Precipitation: including type (snow, rain, ground fog, etc.) and amount 3. Global circulation patterns: both oceanic and atmospheric 4. Continentiality: presence or absence of large land masses 5. Astronomical factors: including precession, axial tilt, eccen- tricity of Earth’s orbit, and variable solar output 6. Human impact: including green house gas emissions, ozone layer degradation, and deforestation http://www.ecn.ac.uk/Education/factors_affecting_climate.htm http://www.necci.sr.unh.edu/necci-report/NERAch3.pdf http://www.bbm.me.uk/portsdown/PH_731_Milank.htm Natural Climatic Variability Natural climatic variability refers to naturally occurring factors that affect global temperatures. -

The Definition of El Niño
The Definition of El Niño Kevin E. Trenberth National Center for Atmospheric Research,* Boulder, Colorado ABSTRACT A review is given of the meaning of the term “El Niño” and how it has changed in time, so there is no universal single definition. This needs to be recognized for scientific uses, and precision can only be achieved if the particular definition is identified in each use to reduce the possibility of misunderstanding. For quantitative purposes, possible definitions are explored that match the El Niños identified historically after 1950, and it is suggested that an El Niño can be said to occur if 5-month running means of sea surface temperature (SST) anomalies in the Niño 3.4 region (5°N–5°S, 120°–170°W) exceed 0.4°C for 6 months or more. With this definition, El Niños occur 31% of the time and La Niñas (with an equivalent definition) occur 23% of the time. The histogram of Niño 3.4 SST anomalies reveals a bimodal char- acter. An advantage of such a definition is that it allows the beginning, end, duration, and magnitude of each event to be quantified. Most El Niños begin in the northern spring or perhaps summer and peak from November to January in sea surface temperatures. 1. Introduction received into account. A brief review is given of the various uses of the term and attempts to define it. It is The term “El Niño” has evolved in its meaning even more difficult to come up with a satisfactory over the years, leading to confusion in its use. -
Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future
Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future As more and more states are incorporating projections of sea-level rise into coastal planning efforts, the states of California, Oregon, and Washington asked the National Research Council to project sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account the many factors that affect sea-level rise on a local scale. The projections show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections; north of that point, sea-level rise is projected to be less than global projections because seismic strain is pushing the land upward. ny significant sea-level In compliance with a rise will pose enor- 2008 executive order, mous risks to the California state agencies have A been incorporating projec- valuable infrastructure, devel- opment, and wetlands that line tions of sea-level rise into much of the 1,600 mile shore- their coastal planning.

Effects of Climate Change on Sea Levels and Inundation Relevant to the Pacific Islands
PACIFIC MARINE CLIMATE CHANGE REPORT CARD Science Review 2018: pp 43-49 Effects of Climate Change on Sea Levels and Inundation Relevant to the Pacific Islands Jerome Aucan, Institut de Recherche pour le Développement (IRD), New Caledonia. EXECUTIVE SUMMARY Sea level rise is a major consequence of climate change. The global sea level rise is due to a combination of the thermal expansion of the oceans (because of their warming), and an increase in runoff from the melting of continental glaciers (which adds water to the oceans). The rate of global mean sea level (GMSL) has likely accelerated during the last century, and projections predict that sea level will be 0.4 to 0.8 m higher at the end of this century around the Pacific islands. Regional variations in sea level also exist and are due to large scale current or climate features. In addition, the sea level experienced on Pacific islands can also be affected by vertical land movements that can either increase or decrease the effects of the rise in GMSL. Coastal inundations are caused by a combination of high waves, tides, storm surge, or ocean eddies. While future changes in the number and severity of high waves and storms are still difficult to assess, a rise in GMSL will cause an increase in the frequency and severity of inundation in coastal areas. The island countries of the Pacific have, and will continue to experience, a positive rate of sea level rise. This sea level rise will cause a significant increase in the frequency and severity of coastal flooding in the near future. -

This study assesses the changes in severe drought characteristics over the Asian monsoon region responding to 1.5 and 2.0 ◦C of global average temperature increases above preindustrial levels. Based on the selected 5 global climate models, the drought characteristics are analyzed according to different regional climate zones using the standardized precipitation index. Under global warming, the severity and frequency of severe drought (i.e., SPI < 1.5) are modulated by the changes in seasonal and regional precipitation − features regardless of the region. Due to the different regional change trends, global warming is likely to aggravate (or alleviate) severe drought in warm (or dry/cold) climate zones. For seasonal analysis, the ranges of changes in drought severity (and frequency) are 11.5%~6.1% (and 57.1%~23.2%) − − under 1.5 and 2.0 ◦C of warming compared to reference condition. The significant decreases in drought frequency are indicated in all climate zones due to the increasing precipitation tendency. In general, drought features under global warming closely tend to be affected by the changes in the amount of precipitation as well as the changes in dry spell length. -
Weather & Climate
Weather & Climate July 2018 “Weather is what you get; Climate is what you expect.” Weather consists of the short-term (minutes to days) variations in the atmosphere. Weather is expressed in terms of temperature, humidity, precipitation, cloudiness, visibility and wind. Climate is the slowly varying aspect of the atmosphere-hydrosphere-land surface system. It is typically characterized in terms of averages of specific states of the atmosphere, ocean, and land, including variables such as temperature (land, ocean, and atmosphere), salinity (oceans), soil moisture (land), wind speed and direction (atmosphere), and current strength and direction (oceans). Example of Weather vs. Climate The actual observed temperatures on any given day are considered weather, whereas long-term averages based on observed temperatures are considered climate. For example, climate averages provide estimates of the maximum and minimum temperatures typical of a given location primarily based on analysis of historical data. Consider the evolution of daily average temperature near Washington DC (40N, 77.5W). The black line is the climatological average for the period 1979-1995. The actual daily temperatures (weather) for 1 January to 31 December 2009 are superposed, with red indicating warmer-than-average and blue indicating cooler-than-average conditions. Departures from the average are generally largest during winter and smallest during summer at this location. Weather Forecasts and Climate Predictions / Projections Weather forecasts are assessments of the future state of the atmosphere with respect to conditions such as precipitation, clouds, temperature, humidity and winds. Climate predictions are usually expressed in probabilistic terms (e.g. probability of warmer or wetter than average conditions) for periods such as weeks, months or seasons. -

IUCN’s mission is to influence, e ncourage and assist societies throughout the world to con- serve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustain- able. IUCN is the world's largest environmental knowledge network and has helped over 75 countries to prepare and implement national conservation and biodiversity strategies. IUCN is a multi- cultural, multilingual organization with 1000 staff located in 42 countries. Its headquarters are in Gland, Switzerland. http://www.iucn.org [email protected] Sustainable livelihoods and ecosystems management For the Preparatory Committee for the World Summit on Sustainable Development - 4 th Preparatory Meeting, Bali (Indonesia) While one cannot say with any confidence what forms an ecological crunch might take, when it might happen, or how severe it might be, it is easier to predict who will have the worst of it. The poor and powerless cannot shield themselves from ecological problems today, nor will they be able to do it in the future. J.R. McNeill, “Something New under the Sun” Introduction As a conservation organization that puts people at centre stage in its mission and vision, IUCN welcomes the new international focus on poverty alleviation. We know from our own experience that the pursuit of enviro nmental goals at the expense of economic well-being and social justice is doomed to fail. -
