Your source for forecasting tools, software, and books since 1993

"Thank you for actually penning these books. They are a wonderful review of the concepts without the excessive (but necessary) amount of math behind them. I wish they had been recommended as supplements in both my undergrad and graduate years."

— Josh Tobias, 2017

"I have used Digital Atmosphere for quite sometime and consider it to be one of the most straightforward, comprehensive, and operationally useful programs on my server. I have found it to be invaluable for my day-to-day analyses and forecasting as well as my ongoing research. Tim is also extremely helpful and absolutely indispensable when it comes to locating scripts, the best datasets, and even professional contacts to help make any organization as productive as possible."

Chris Robbins, iWeatherNet

"The quality of your products is second to none."

— C. Brian Batey

"Thanks Tim for your quick response (we like that at FedEx) about our Professional Versions! As we're a 24/7 operation, we're look forward to augmenting our present weather system with Digital Atmosphere."

— Mel Bradley, FedEx Operations

"Wow. Your books are incredibly technical and useful. I consider myself a very amateur weather watcher and feel that I am already ahead of the curve. Thank you."

— Terry W. Taylor

"The NEXRAD support is truly awesome and easy to use - and the other feature just really tops it off. This is about my sixth email tonight - the other five being to other spotters in the area telling them they just have to download Digital Atmosphere and give it a serious going over."

— David Cashion

"I'm really looking forward to the next phase of Digital Atmosphere Workstation. I'm sure it will be as excellent as all your other products."

— Simon Keeling
Weather Consultancy Services, UK

"I run and manage a number of festival type events and Digital Atmosphere is able to produce charts that I can use for normal weather forecasting with a fair degree of accuracy and in particular wind speed and direction that is crucial to many of events."

— Robert Connolly, GI7IVX

"The archive data arrived today. WOW! What an amazing set of data! Thanks again for all the extras that you included as well!"

— Bryan Bollman, IA

"We do run GEMPAK and all the Unidata software also, but your package has numerous advantages, the biggest being Windows."

— Anonymous

"I am very impressed with what you have done. I have already shown several people at work your site. I plan on talking to our MIC [Meteorologist In Charge] soon to see if we can get Digital Atmosphere in the office to complement/supplement AWIPS."

— Ken Simosko, NWS, Pocatello

"This new version is even better than the older version which was awesome! Your programming skills and met knowledge amaze me!"

— Chris Kincaid

SPECIAL NOTE: Customers needing a copy of Weather Analysis & Forecasting Handbook First Edition (originally sold 2011-2021) may obtain a copy at this link for a limited time, or until copies are depleted.

Weather Analysis & Forecasting Handbook is the ultimate guidebook for anyone who needs to know the details of operational weather analysis and forecasting, not just theoretical aspects and basic concepts. It is written for actual forecasting without difficult math or a extensive review of physics and weather history.

This 2021 revision contains an extensive update of numerical modeling, bringing readers the latest on models like the GFS, ECMWF, and HRRR models. The content covers the same concepts and techniques that National Weather Service forecasters practice on a daily basis. Among those who will enjoy the title are meteorology professionals, students, pilots, flight dispatchers, amateurs, storm chasers, and spotters. Note that this is not a rewrite of the earlier 2011 version, but numerous sections throughout the book have been updated. The most extensive revisions are found in the modeling, radar, and satellite chapters.

Basic physical concepts are reviewed, and then the book covers thermodynamics, surface analysis, and upper analysis. There is a thorough overview of weather systems, including their thermal structure, dynamics, and effects. Special problems such as thunderstorms, winter weather, and tropical weather are treated in detail. The margins are filled with forecasting facts, hard-hitting quotes, educational stories, and even a few fun weather jokes. With added emphasis on analysis, visualization, and awareness of model limitations, readers learn to use tools properly and are always a step ahead.

Weather Analysis & Forecasting Handbook is the perfect companion to our other title, Weather Map Handbook Handbook, and our meteorologist's desk reference Weather Forecasting Red Book. It replaces the Weather Forecasting Handbook, though we will continue to make the former title available to those who want to collect it.
