Project
Weather Forecast App
INTRODUCTION
Weather forecasting is the application of science and technology to
predict the conditions of the atmosphere for a given location and time.
Human beings have attempted to predict the weather informally for
millennia and formally since the 19th century. Weather forecasts are made by
collecting quantitative data about the current state of the atmosphere at a given
place and using meteorology to project how the atmosphere will change.
Once a human-only endeavor based mainly upon changes in barometric
pressure, current weather conditions, and sky condition or cloud cover, weather
forecasting now relies on computer-based models that take many atmospheric
factors into account. Human input is still required to pick the best possible
forecast model to base the forecast upon, which involves pattern recognition
skills, tele-connections, knowledge of model performance, and knowledge of
model biases. The inaccuracy of forecasting is due to the chaotic nature of the
atmosphere, the massive computational power required to solve the equations
that describe the atmosphere, the error involved in measuring the initial
conditions, and an incomplete understanding of atmospheric processes. Hence,
forecasts become less accurate as the difference between current time and the
time for which the forecast is being made (the range of the forecast) increases.
The use of ensembles and model consensus help narrow the error and pick the
most likely outcome.
There are a variety of end uses to weather forecasts. Weather warnings
are important forecasts because they are used to protect life and property.
Forecasts based on temperature and precipitation are important to agriculture,
and therefore to traders within commodity markets. Temperature forecasts are
used by utility companies to estimate demand over coming days. On an
everyday basis, people use weather forecasts to determine what to wear on a
given day. Since outdoor activities are severely curtailed by heavy rain, snow
and wind chill, forecasts can be used to plan activities around these events, and
to plan ahead and survive them.
PURPOSE
The purpose of this project is to design and built a fully functional weather
application. It also includes the fetching of the data in need of taking
information about weather worldwide thus will display accurate weather
forecast to user’s given location in an efficient and effective manner.
SCOPE
The scope of this project lies in collecting and display of local weather data,
analyze weather forecast and display a live stream of the local weather. The
product will be able to predict the weather. It will also display many other
factors like humidity, chances of rain (in percentage) and also live condition of
weather (Sunny, cloudy, rainy or snowy).
The project is basically an android application thus, will be available on
smartphones only. The goal of this project is to provide accurate weather
forecast for every city in the world.
OBJECTIVES
The objectives of this project are as followed:
To fetch the accurate and precise values of information about weather.
To analyze correct amount of data or information of weather.
To display of weather accordingly to city (location).
To display of live weather forecast in very much accurate and precise data.
To cover out all the cities of the world via GPS.
To provide quick service to user.
To provide an information chart of weather forecast.
To show some more factor that affect the climate changes like humidity,
wind speed and pressure).
To provide a user friendly interface which will provide ease to user to get
information about weather forecast easily as possible.
FUCTIONAL REQUIREMENTS
Search through City Name:
When searching for a location to display its weather, the app allows users to
search using city names. This will make it easy for most users to use the app
quickly enough when looking for a desired location.
Advance Weather Prediction:
While users can monitor the current weather, they will also have access to a 7-
day in advance weather prediction for their searched and stored cities.
Location Changes:
User can also able to change or remove the locations.
Weather Forecast:
The system will get forecasted weather conditions and display onto the screen.
Current Weather
The system will retrieve the current weather conditions and displays onto the
screen.
Forecasting Accuracy:
The system will retrieve the forecasted weather conditions and measures the
accuracy of said predictions.
NON FUCTIONAL REQUIREMENTS
Maintainability
The attributes that will help to maintain the system is clean code.
Application should be economically feasible. User can get all information
related to weather easily.
Availability
The availability of the system is that the app will be active on the Internet.
Application must also run or provide the saved information in offline mode.
Usability
The application should be user friendly and should require least effort to
operate.
Reliability
The reliability of the system is to make sure the application must run on
online or offline mode. This app is compatible so that you can run it at any
operating environment. This app don’t use much ram of your phone so that you
can easily install in your phones or tablets.
Performance
The software shall support use of multiple users at a time and does affects
load time. Response time is very fast so data can be accessed as quickly as
possible.

CONCLUSION
By this system weather forecasting report generation becomes easy. Less
chances of malfunctioning are there. The system has reached a steady state but
still improvements are to be made. The system is operated at a high level of
efficiency and all the work and user associated with the system understand its
advantage. It was intended to solve as requirement specification. In future this
system can be implemented to all over the world and will be designed for cross
platform.
