Compendium on Tropical Meteorology for Aviation Purposes
This Compendium is intended for use by airport and airspace planners and designers, air traffic controllers and flight crew to improve their knowledge of the basic processes governing weather in the tropics as well as the detailed climate and weather of the individual regions in and adjacent to the tropics. This Compendium can also be used by operational and non-operational meteorologists, including aeronautical meteorological observers and forecasters, as well as meteorological training professionals as valuable reference material and a training aid.
Change of diurnal precipitation in different phases of Bsiso
As we know tropical intraseasonal oscillation (ISO) was described as 2 modes such as Boreal summer intraseasonal oscillation (BSISO) during boreal summer and Madden-Julian Oscillation (MJO) dominates during boreal winter. In summer time, Thailand where located at the coastal region at the Equator which is effected by BSISO. Some week there is strong diurnal cycle but some week is opposite. The purpose of this work is to study the evolution of BSISO and to study the change of diurnal precipitation in different phases of BSISO. Tropical Rainfall Measuring Mission (TRMM) version 3B42 data on 0.25 ...
Introduction to Tropical Meteorology, 2nd Edition: Chapter 6 Vertical Transport
This chapter examines vertical transport of heat, moisture, momentum, trace gases, and aerosols, including the role of tropical deep convection and turbulence. Diurnal and seasonal variations in surface fluxes and boundary layer depth are examined. The boundary layer is compared over the ocean, humid, and dry tropics, including its role in dispersing chemicals and aerosols. Boundary layer clouds are examined in terms of their connection to sub-cloud layer properties. Comparisons are made between heat and moisture transport under a variety of convective modes such as mesoscale convective system ...
Introduction to Tropical Meteorology, 2nd Edition: Chapter 7: Synoptic and Mesoscale Systems
In this chapter, we examine the wide-variety of synoptic and mesoscale weather systems that affect the tropics, including, tropical easterly waves, upper tropospheric troughs, monsoon depressions, subtropical cyclones, westerly wind bursts, and cold fronts. Extratropical interactions, such as those caused by Rossby wave trains and the MJO, are examined. The chapter presents a review of thunderstorms and lightning. The structure, formation mechanisms, and impacts of mesoscale convective systems are examined. The distribution of lightning globally and within mesoscale systems is examined. Mesosc ...
Regional Study Guide: Review for Aeronautical Forecasters in Africa, selections from Introduction to Tropical Meteorology, 2nd edition
This Regional Study Guide highlights the sections of the Introduction to Tropical Meteorology, 2nd Edition online textbook that are applicable to aeronautical forecasting operations in Africa. Topics include remote sensing, global circulations, tropical variability, tropical cyclones and the challenges encountered when forecasting tropical weather. The guide consists of a list of links to the content in the textbook and has its own stand-alone quiz.
TCP, 52. Proceedings of the International Workshop on Satellite Analysis of Tropical Cyclones
The first WMO International Workshop on Satellite Analysis of Tropical Cyclones (IWSATC) was organized by the WMO Tropical Cyclone Programme (TCP) in collaboration with the WMO World Weather Research Programme (WWRP), and the World Data Center (WDC) for Meteorology which is maintained by the National Oceanic and Atmospheric Administration (NOAA). The main purpose of IWSATC is to increase the accuracy and reliability of satellite analyses of tropical cyclones (TCs) by sharing the latest knowledge and techniques amongst operational forecasters of the major warning centers and researchers. The or ...
WWRP, 2011-1. 7th International Workshop on Tropical Cyclones (IWTC-VII)
Since November 1985, WMO has organized a series of quadrennial International Workshops on Tropical Cyclones (IWTCs), the latest of which took place in La Reunion (France) from 10 to 15 November 2010. It is noteworthy that this seventh WMO International Workshop on Tropical Cyclones (IWTC-VII) has been the first held in WMO Regional Association I (Africa). The Workshop primary objectives were to review progress in tropical cyclone research and operational practices since IWTC-VI and to contribute in identifying future research and operational priorities. The six-day meeting set the scene for ex ...

WWRP, 2011-3. WWRP/ETRP Workshop on Operational Monsoon Research and Forecast Issues : lecture notes
CAWCR technical report, 46. Abstracts of the Fifth International Verification Methods Workshop, 1 - 7 December 2011, Melbourne, Australia
This year's scientific workshop offers a stimulating and informative array of presentations on forecast verification relevant to a variety of topics including ensemble and probability forecasts, seasonal forecast and climate projections, aviation forecasts, user-focused verification, tropical cyclones and high impact weather forecasts and warnings, as well as methodologies and issues that apply to many areas. The workshop features five keynote talks by international experts, as well as a public lecture by renowned climate researcher, Professor Neville Nicholls of Monash University on, "Can wea ...
Introduction to Tropical Meteorology, 2nd Edition, Chapter 3: Global Circulation
The chapter begins with a review of the general principles of atmospheric motion including scale analysis of tropical motions. An overview of the general circulation of the atmosphere and ocean is presented including stratospheric general circulation. Special emphasis is given to the Hadley circulation including its maintenance, seasonal migration, northern and southern hemispheric differences, and the contrast between tropical and midlatitude wind systems. Tropical circulations are examined in a theoretical framework as responses to heating at the equator. Regional monsoons, their conceptual ...
Introduction to Tropical Meteorology, 2nd Edition, Chapter 8: Tropical Cyclones
Tropical cyclones are the deadliest tropical weather systems. This chapter describes their seasonal and geographic variability and controls, decadal cycles, and history of naming conventions. Tropical cyclogenesis is explored in depth and the core and balance solutions for regions of the cyclone are examined. Intensity is considered in terms of inner-core dynamics, large-scale environmental controls, limits on potential intensity, satellite interpretation techniques, and classification by wind speed. Factors that influence motion are investigated. Extratropical transition is described in terms ...
Introduction to Tropical Meteorology, 2nd Edition, Chapter 4: Tropical Variability
This chapter presents an overview of the major cycles dominating intraseasonal and interannual variability in the tropics. Characteristic atmospheric and oceanic patterns for each oscillation are presented and methods for tracking the evolution of these cycles are described. Observations and conceptual models of equatorial waves are presented. Classical solutions for equatorial waves are outlined and the effects of moisture on the expression of these waves are discussed. Since the tropics are not an isolated region of the globe, the impacts of these cycles on higher latitudes are also explored ...
Introduction to Tropical Meteorology, 2nd Edition, Chapter 2: Tropical Remote Sensing Applications
This chapter covers remote sensing, the primary method of observing weather and climate across the global tropics. Learners will become familiar with the scientific basis and applications of radar and satellite remote sensing from examples in which clouds and precipitation are observed by measuring microwave signals using ground-based radar, spaceborne radar, and satellite radiometers. Wind estimation, dust and volcanic ash tracking, vertical sounding techniques, and remote measurement of sea-surface, soil and land surface properties are also covered.
Introduction to Tropical Meteorology, 2nd Edition, Chapter 5: The Distribution of Moisture and Precipitation
Moisture and precipitation distribution governs life in the tropics. Surplus heating and rising motion in the tropics ignites the global water and energy cycles and influences weather in the midlatitudes. This chapter presents the horizontal and vertical distribution of water vapor, tropical cloud formation and distribution, the lifecycle and precipitation characteristics of tropical mesoscale convective systems, and the variability of tropical precipitation on yearly, seasonal, and hourly time-scales.
