How do I get a weather forecast updated on my about-to-be-created weather app?
That’s not a rocket science - all you should do is to integrate an API into your application. Just for reference, an API is a kind of bridge that connects your application to some external services, in our case these are weather forecasts.Moreover, your choice is almost unlimited. There are many weather APIs - OpenWeatherMap, AccuWeather, Weather Underground - just to name a few. Which one to choose? Well, this depends on your budget and needs (for example, what kind of data you’re expecting to get; if you just need real-time forecasts almost any API will fit).Image by HYZI also recommend you to read the article “How to Make a Weather App”. It lays everything regarding weather app development out and, it seems to me, will be quite useful to you :)
How do I run my own weather forecast similar to what the NOAA does? Are the models open-source?
As far as I know the The Weather Research&Forecasting Model Website is an open source model used by NOAA. You can get local forecasts to your region. You can also get the forecasting output from GFS and so WRF + GFS allows you to get forecasts for your little micro climate if you feel inclined for it.Now I have my issues with WRF which is a sophisticated model but with forecast of questionable quality in my opinion. At least I think people do not check enough the quality of their forecasts with altimeter, radar stations and other measurements (which are also available on NOAA web site if I am not mistaken).Now, in recent times the European models have been better (see in particular Meteorological history of Hurricane Sandy - Wikipedia) and the IFS model used at ECMWF has been the best. If you want the ECMWF forecasts then you need to pay. But the model can apparently been accessed for free at OpenIFS Home - OpenIFS - ECMWF Confluence Wiki. In contrast to WRF, IFS is a global model for the whole earth, so it is different purpose.There are plenty of other possibilities. See for example Data Sources and use google.
Can deep learning be used to forecast weather?
Sure, but your results would depend largely on the granularity of your input vector. Remember that neural networks map inputs to results by uncovering hidden (Deep) relationships between the two. One can imagine a deep learning system that took in barometric readings from distributed weather stations and used that data to learn the direction the wind blows under certain conditions. However, you may soon discover that wind is also a function of temperature, geography and any number of other features.There within lies the challenge of building weather models. Weather is a vastly complex network of inputs and your learning algorithm is only going to be as good as the correct inputs that you've selected to train on. Select a fine enough set of inputs and you are basically attempting to teach your learning algorithm fluid dynamics. Achievable, but computationally demanding. In conclusion, weather isn't one thing, to make the problem tractable, It's advisable to select some subset of weather features you want to make predictions about.P.S. Not quite weather, but people have began using deep learning to solve fluid dynamics problems that arise in plasma flows during nuclear fusion.Page on twicaagt.ugent.be
How do I create a weather forecast model in C++?
Answering this question would be basically writing your code for you. Sorry dude, ask a meteorologist for all of the variables, and make sure to input the historical data for each variable data set. The if’s/and/or/but’s is all you. A program like this will take thousands of man hours. Good luck and God Speed sir!

How can I make 7 days forecast weather app using Android?
You can connect with a API FEED. There are many public and private weather data providers, such as AccuWeather, Environment Canada, NOAA, Govt’s and much more.At this point it really depends the type of data you want to integrate within you app. Some data from private providers are PAID and from government are FREE. The feed from the private is generally a better quality API for the price.Here’s what you can do :Choose a provider that can feed reliable and quality dataDesign your app using Android StudionCreate an API call that received push notifications or RSS feed within you appScript that incoming data (generally XML or TXT) to show it the way you want in the appReview with GoogleLaunch!
Why isn't machine learning used for weather forecasts?
To forecast the weather, you must first gather, as many as possible, current observations. That is what the World Meteorological Organization (WMO) - a division of the United Nations - is doing, every day.That creates a synoptic map, a snapshot of the present situation.From that, national organizations such as the NOAA in the USA, feeds it to a computer model such as the Global Forecast System (GFS) or the UKMO in Britain or, the YRNO in Norway, etc.From that, using Machine Learning algorithms and Computational Fluid Dynamic (CFD) it estimates a forecast within a cone of probability. Simple, isn’t it?The interesting point is that, weather forecasting only became possible after the invention of the telegraph, when many observations could be gathered at once. To start with, the Société des Nations did the job of gathering international observations then, the United Nations and the WMO. This was working, even during war time, because all parties involved wished to get as accurate as possible weather forecast. During the Second World War, Germans and Englishmen met in Lisbon, in neutral country, to exchange such information.

How do temperature, dew point, and wind direction contribute to the day's severe weather?
Good question, Jessica! All of the things you mentioned have a significant impact on severe weather and where severe thunderstorms develop. When you have very warm temperatures at the ground on a sunny day you can have very cold temperatures high in the atmosphere. The first ingredient to having severe thunderstorms is that you need to have steep "lapse rates" in the atmosphere. Lapse rates are special zones in the atmosphere where temperatures change dramatically with height. Where you have these higher rates of change, you have more instability and that creates the scenario for severe thunderstorms. When the dew point surges into the lower to mid 70s, there's plenty of moisture at the ground for thunderstorms to work with. As you may know, clouds are just made up of microscopic ice crystals which is frozen water vapor. The more moisture you have at the ground, the more water vapor can be generated and the clouds can undergo processes that make them grow larger and faster. When there's more moisture to work with, thunderstorms literally take in all this moisture and can maintain their intensity. Winds play a crucial role in the situation. Ultimately, winds assist in fueling the thunderstorm's updrafts. The updraft is what keeps a thunderstorm alive, by pumping in more warm air and maintaining condensation at the top of the cloud. Winds can carry warm moist air and use it to create thunderstorms. If you have wind shear in the atmosphere (winds which change direction with respect to height), then you pose the risk for tornadoes to form. Each of these things plays a very important role in severe thunderstorm formation. Warmer temperatures combined with high dew points and strong wind shear can generate massive thunderstorms capable of producing very large hailstones and even tornadoes. Hope this helps you!
