Description

Weather4D Lite is a powerful meteorological application based on atmospheric and oceanic data in GRIB format. It benefits from a new interface derived from the “Routing and Navigation” version.
Over 35 weather and oceanographic forecast models are available. Queries and downloads are fully customizable.
The application makes it possible to create your own geographical zones and to select the characteristics of the GRIB files to download: choice of data, resolution, periodicity, file size, etc.
GRIB files are downloaded from APP4NAV’s own servers, but can also be obtained by satellite phone.
Weather4D Lite displays the combined data as layered layers, and fine-tunes the mode and display quality of each data type. All the data of a selected model is displayed by an animation in continuous time scrolling or in manual scrolling on the chart.
The weather forecast is displayed in one or two windows (iPad only), offering several display combinations of the same area: weather forecast and wave or current forecast, comparison of different models. The two windows can be disassociated for displaying the same area at different scales.
Weather4D Lite comes standard with the GFS global forecast model at 0.25 °, 0.5 °, 1 ° and 2 ° resolutions. Two global satellite (BING) and global terrestrial (Open Street Map) cartographies.
Options
High resolution weather models NAM, COAMPS, WRF (USA), GEM (Canada), ARPEGE Global, ARPEGE Europe, AROME, AROME HD (France), AROME (DOM-TOM), as well as wave models WW3 and MERCATOR OCEAN and currents models MFWAM, NCOM are provided in a single pack available by annual subscription (in-app purchase).

Most useful weather app that I

This is without a doubt a great weather app. In fact, I’ll go as far as saying that it’s the best that I’ve seen.

I’ve downloaded many different weather apps and this one has become my favorite. It combines a lot useful information, which is typically viewed separately from multiple sources; I especially like how I can view a lot of important data over-laid at the same time, in a very efficient manner. The user interface is also very intuitive making the app easy to use. Prior to owning this application I found myself switching back and forth between different types weather maps. The only feature that I hope will someday be added is a way to overlay the numerical value of ocean wave heights, currently ocean wave period predictions can be viewed but wave heights can only be viewed via color gradients.

I believe that anyone who needs to, or simply enjoys, forecasting the weather will love this app.

A beautifully-designed app for NOAA GFS data

Weather4D is a beautiful app for examining output from the NOAA Global Forecast System (GFS), which is the basis for most U.S.-based weather forecasts. The user interface is elegant on both the iPhone and the iPad and has many thoughtful features, such as the land and sea masks and the way, when looking at further out forecasts, that the clock icon is shaded in proportionally to the time since the model was run.

I haven't encountered any bugs, and I appreciate that app comes with a comprehensive user guide.

One thing that I would like to see added is the option to display scale bars for the shading (e.g., the temperature scale corresponding to the temperature shading). Overall, however, Weather4D is a wonderful app.

Truly Amazing

This is a wonderful app!
As a pilot and flight instructor I use this app for long term prediction. The graphical interface has almost limitless settings for including or removing visible data. I have been disappointed by every weather app I've downloaded, until this. Lives on my home page. (Did the negative reviewers even understand the most basic aspects of weather prediction?) If you want simple idiot mode weather, most other apps will be fine. If you want beautifully depicted graphical prediction models, this is it.
