Smart Climatology – Prototype Operational Products Typical:October–November is the “short rains” season in the Horn of Africa, characterized by extensive cloud decks, showers and isolated, afternoon thunderstorms. For typical years in the Addis Ababa area, moderate impacts to collections and RQ1B operations are assessed in October and early November, improving to mostly favorable after the mid-November end of the rainy season. RQ1B launch and recovery operations out of Camp Lemonier are assessed as favorable overall, with occasional impacts from afternoon crosswinds and extreme afternoon temperatures exceeding operational thresholds. El Nino:A strong El Nino event would tend to increase showers, cloud cover and thunderstorm activity in October-November. ISR impacts will tend to worse than in the typical year. Assessment for ISR is moderate to occasionally unfavorable. Assessment of RQ1B launch and recovery operations out of Camp Lemonier remains the same as in typical years. La Nina:A strong La Nina event would tend to suppress showers, cloud cover and thunderstorm activity during Oct-Nov. ISR impacts will tend to general improvement over typical years. Assessment for ISR is the same as for the typical year, but expect thunderstorm and shower frequency to decrease. Assessment of RQ1B launch and recovery operations out of Camp Lemonier remains the same as in typical years. Legend • Cloud cover 2. Precipitation 3. Winds 4.

Back-Up and Background Discussion Slides Smart Climo, Murphree@nps.edu, Sep 06
Overview NPS Smart Climatology Program Tom Murphree, Ph.D. The typical process of developing military climatology products relies heavily on traditional methods of climate analysis, and excludes many modern methods of climate analysis and forecasting. This means that very few military climatology products account for climate variations (e.g., El Nino, Madden-Julian Oscillation), or for the many advances over the last 30 years in climate data sets, monitoring, analysis, modeling, and forecasting. Thus, Air Force Weather and Naval METOC units, and the combatant commanders they serve, lack state-of-the-art climatological support. To address this shortcoming, we are conducting a long term program to develop, adapt, and transition to operational use systems for developing state-of-the-art military climatology, also known as smart climatology. Our goal is to assist in closing the gap between (a) present climatological support for military operations and (b) the support that is achievable through the application of modern methods of climate analysis and forecasting. Because of the wide application of climatology in the development of both climate and weather products, we expect smart climatology products to benefit combatant commanders at all planning levels (strategic, operational, and tactical). The primary goals of our smart climatology program are to: (1) develop scientific products for use in developing operational products; (2) develop operational planning products based on the scientific products; and (3) deliver scientific and operational products via a web-based (net-centric) platform. Our primary scientific products are analyses of the regional atmospheric and oceanic impacts of climate variations (e.g., El Nino, La Nina, Madden-Julian Oscillation, Indian Ocean Zonal Mode, North Atlantic Oscillation). The focus regions for our work thus far are southwest Asia (SWA), the Horn of Africa, east Asia, the western tropical North Pacific, the northeast Pacific, and North America. Our main operational products are prototype assessments of operational impacts derived from: (a) our climate analyses; and (b) applying a set of forecaster guidelines that we have developed for providing smart climatology support. We have recently begun a climate forecasting effort based on our climate analyses for SWA and using composite analysis methods. We are currently developing web-based methods of product delivery. Our program is based on a collaboration of Naval Postgraduate School (NPS) faculty and staff, Air Force and Navy students at NPS, and climate research and development contractors. We are also coordinating and collaborating in our smart climatology efforts with the Air Force Combat Climatology Center, Fleet Numerical Meteorology and Oceanography Detachment Asheville, and civilian colleagues in climate research and operational climatology. Reports on our program are available at: http://wx.met.nps.navy.mil/smart-climo/reports.php For more information on the NPS Smart Climatology Program, please contact the program director, Dr. Tom Murphree at: murphree@nps.edu Smart Climo, Murphree@nps.edu, Sep 06
Definitions Traditional Climatology Climatology that focuses on long term means, especially the description of long term mean (LTM) seasonal cycles. Traditional climatology deals little, or not at all, with variations from the long term. Modern Climatology Climatology that addresses LTM patterns and climate variation patterns, with a focus on describing both the patterns and the processes that drive those patterns. The study of climate processes includes the development and application of methods for monitoring, modeling, and forecasting the climate system. Examples of climate variations: El Nino La Nina-Southern Oscillation, Madden-Julian Oscillation, North Atlantic Oscillation. Smart Climo, Murphree@nps.edu, Sep 06
Traditional Climatology Versus Modern Climatology The reliance on LTMs to describe the climate system means that traditional climatology is unable to account for climate variations that can significantly alter the state of the climate system and impact deployment planning and combat operations (e.g., weapons selection, force positioning, and operational planning). The focus on patterns rather than processes means that traditional climatology contributes relatively little to the dynamical understanding of LTM patterns, or to the analysis and forecasting of climate variations. Thus modern climatology provides a more comprehensive view of the climate system and is much better suited than traditional climatology for supporting combatant commanders. Smart Climo, Murphree@nps.edu, Sep 06
Climatology in Support of Combatant Commanders Problem DoD climatology products are based almost exclusively on traditional climatology. This means combatant commanders have far fewer useful climo products than are available in the civilian sector or that could be readily adapted for DoD use. Approach to Solving Problem Adapt and apply modern, or smart, climo methods and products for use by combatant commanders (e.g., adapt and apply climate analysis and forecasting methods and products used in civilian sector). Smart Climo, Murphree@nps.edu, Sep 06
Smart Climatology = Modern Climatology Smart Climatology Climatology that includes LTMs but also accounts for: a. higher order statistics than the LTM b. modern developments in climate science and operational climatology By this definition, smart climatology could also be called modern climatology. Modern climatology is an apt term, since DoD climatology is way behind the times. Civilian climatology is far more advanced than military climatology, in terms of: 1. climate science 2. development and application of operational climatology methods and products This lag in DoD climatology has created significant gaps in climatological support for war fighters. Smart Climo, Murphree@nps.edu, Sep 06
Statement of Problem • Warfighters are not getting the full benefit of proven operational • climatological data and methods because: • 1. DoD climatology is behind the times. • 2. Long term mean climatology is not sufficient for DoD planning and operations. • 3. Information is often not: (a) up to date; and/or (b) available at sufficient spatial / temporal resolution for area or period of interest. • 4. A lot of very relevant climo information, methods, and products are not yet readily available to METOC personnel or their customers. • a. not yet adapted for military use • b. no central, easily accessible source • 5. It is difficult to translate climo information into environmental impacts on operations, and such translations are rarely provided in off-the-shelf climo products. • 6. METOC units must interpret available climo information to fit their individual needs. • a. too time consuming and labor intensive • b. much of this tailoring would be more efficient and • effective if done by experts at a central location • c. units’ time is better spent tailoring smart climo to the needs • of combatant commanders Smart Climo, Murphree@nps.edu, Sep 06
Needed: Smart Climatology Capabilities • 1. Need environmental data from multiple sources that are physically consistent and up-to-date (e.g., latest observations and forecasts available for inclusion in climo products). • 2. Need higher spatial and temporal resolution. Most climo products, especially ocean products, have poor or marginal resolutions. • 3. Need a web based, readily accessible, interactive system for analyzing, displaying, and down loading climo information for the global environment. System needs extensive user functions (e.g., analysis functions for compositing, differencing, correlating; display functions for generating time series, layering data, GIS output). • 4. Need to be able to readily account for climate variations and climate forecasts (e.g., El Nino / La Nina, North Atlantic Oscillation, Madden-Julian Oscillation, etc.). Presently, almost all DoD climo support is based on just LTMs. • Need to feed smart climo to models that currently use only traditional climatology (e.g., LTMs as initial or expected extreme conditions). • Need system for objectively assessing climatological risks and opportunities for war fighters.

Impacts of Climate Variations on Tropical Cyclone Activity: East Asia and Western North Pacific, October H L Smart Climo, Murphree@nps.edu, Sep 06 L H L H H L Upper tropospheric height anomalies associated with El Nino (EN) and La Nina (LN) periods. These height anomalies indicate anomalies in steering flow for tropical cyclones (TCs)., with more recurving TCs during EN and more straight runners during LN. This indicates that, for example, Taiwan (Korea) is more likely to be hit by TCs during LN (EN) years. NPS researchers have shownthat TC formation sites, tracks, and intensities are affected by EN and LN climate variations that are not accounted for in LTM climatologies. Figures from Ford, B., 2000.

Smart Climo and Regime Based Forecasting Smart climo gives you a better insight into the large scale (continental scale to global scale) patterns and processes that, to a large extent, govern the development of the regimes. Climate dynamics governs the uppermost portion of the forecast funnel. So, you can do a better job of analyzing and forecasting synoptic and mesoscale circulations when you understand the low frequency, large scale dynamics that are the subject of climate dynamics. For example, when you understand the tropical climate variations that excite changes in the extratropical Rossby wave field, that in turn lead to changes in extratropical long wave patterns, that then alter synoptic and mesoscale circulations and regimes. A smart climo approach could contribute a fair bit to improving regime based forecasting methods. Many climate variations have well established regimes of their own (often described in terms of teleconnections patterns and processes) that climate-oriented weather forecasters already use in developing medium range forecasts. NWS extended range forecast discussions based on EN, LN, and MJO are one example of this. Many climate variations have known tendencies to make certain medium range and synoptic patterns more or less likely (e.g., tendencies to develop high zonal index flows, blocking patterns, persistent warm moist advection, etc.). Smart Climo, Murphree@nps.edu, Sep 06
Smart Climo and Regime Based Forecasting The mechanisms by which climate variations set up these patterns is often an alteration of the upper tropospheric long wave pattern (shifts in location, changes in wave length and amplitude, etc.), changes in the low level eddies and circulation (e.g., Siberian High, Aleutian Low, Azores High), and associated low level WAA, CAA, moisture advection, moisture convergence, etc. The Stepanek and Vorhee's theses provide some nice tropical and extratropical examples of this. The connection between synoptic and climate processes is also a two-way street (e.g., EN affects the intensity and recurvature of tropical cyclones in the NW Pac, which leads to anomalies in the extratropical long wave pattern over the N America, which alters synoptic systems there). Smart Climo, Murphree@nps.edu, Sep 06
Smart Climo and Regime Based Forecasting There are a variety of smart climo based tools that could be used to improve how regime concepts are used in forecasting. Compositing and principal components could be used to identify the major regime signals associated with climate variations (including their relative amplitudes and phasing). Here, by regime signal, I mean the regimes that are forced by and characteristic of a given climate variations, and the fluctuations of regimes that are separate from but affected by the climate variations. By climate variation, I'm thinking of phenomena such as EN, LN, IOZM, MJO, NAO, but also of simpler, more generic variations such as changes in the zonal index of the extratropical upper tropospheric flow. Cluster analysis could be used to identify the most probable sequencing of the major regime signals (see Jeff's discussion of solutions A, B, and C, below). A variety of other tools could be used to identify the relationships between a given regime and a larger scale variation, and the predictability of the regime given the existence of the variation.

Topics include: (1) statistical, dynamical, and numerical modeling methods used in operational climate analysis and forecasting; (2) advanced analyses of regional and local climate patterns and processes in areas of DoD interest; (3) strategic implications of long term global climate change; (4) role of climatology in strategic to tactical level planning of military operations; (5) assessments of NOAA, Air Force, and Navy climatology methods and products; (6) evaluation of joint military climatology planning tools; and (7) student development of climatology products and planning tools based on civilian and military methods and products. For fall 2006, one of the main topics will be Southwest Asia climate, especially climatological patterns and processes, interactions between weather and climate phenomena, and climate predictions, in particular, predictions for military operations. This course places a strong emphasis on the applications of climate science to military operations. Some aspects of this course may require that students have a secret clearance. The course focuses on the atmospheric component of the climate system, but also addresses the oceanic component at some length. The oceanic and/or land components will be addressed in greater depth if there is sufficient student interest. Pre-requisites: MR 3321 and 3222 (or equivalent courses form another university), a more advanced course (e.g., MR 3234, MR 3252), or consent of instructor. Students are also strongly encouraged, but are not required, to take MR 3610 before MR 4250. Copies of course materials available on request Smart Climo, Murphree@nps.edu, Sep 06
