- SOFTWARE REQUIREMENT – Microsoft Word
- HARDWARE REQUIREMENT – Computer, Keyboard, Mouse, CPU THEORY: - Weather forecasting is the prediction of the state of the atmosphere for a given location using the application of science and technology. This includes temperature, rain, cloudiness, wind speed, and humidity. Weather warnings are a special kind of short-range forecast carried out for the protection of human life. Weather warnings are issued bye governments throughout the world for all kinds of threatening weather events including tropical storms and tropical cyclones depending upon the location. The forecast may be short-range or Long-range. It is a very interesting and challenging task. This module provides a basic understanding of the purpose and scope of weather forecasts, the basic principles, and the general models developed for forecasting. Introduction: Weather forecasting means the prediction of the weather through the application of the principles of physics, supplemented by a variety of statistical and empirical techniques. PROBLEM STATEMENT: - If it is true, as every scientist believes, that subsequent atmospheric states develop from the preceding ones according to physical law, then it is apparent that the necessary and sufficient conditions for the rational solution of forecasting problems are the following: 1.A sufficiently accurate knowledge of the state of the atmosphere at the initial time. 2.A sufficiently accurate knowledge of the laws according to which one CONCLUSION: -

REQUIREMENTS: - 1.SOFTWARE REQUIREMENT – Microsoft Word 2.HARDWARE REQUIREMENT – Computer, Keyboard, Mouse, CPU THEORY: -
1. Data Flow Diagram (DFD) A Data Flow Diagram (DFD) is a traditional visual representation of the information flows within a system. A neat and clear DFD can depict the right amount of the system requirement graphically. It can be manual, automated, or a combination of both. It shows how data is entered and leaves the system, what changes the information, and where data is stored. The objective of a DFD is to show the scope and boundaries of a system as a whole. It may be used as a communication tool between a system analyst and any person who plays a part in the order that acts as a starting point for redesigning a system. The DFD is also called as a data flow graph or bubble chart. 1.1 The following observations about DFDs are essential: All names should be unique. This makes it easier to refer to elements in the DFD. Remember that DFD is not a flow chart. Arrows is a flow chart that represents the order of events; arrows in DFD represents flowing data. A DFD does not involve any order of events. Suppress logical decisions. If we ever have the urge to draw a diamond-shaped box in a DFD, suppress that urge! A diamond-shaped box is used in flow charts to represents decision points with multiple exists paths of which the only one is taken. This implies an ordering of events, which makes no sense in a DFD. Do not become bogged down with details. Defer error conditions and error handling until the end of the analysis.

Process Performs some transformation of input data to yield output data. Source or Sink (external entity) A source of system inputs or sink of system outputs. Data Store A repository of data , the arrow heads indicate the net input and net output to store. ● Circle: A circle (bubble) shows a process that transforms data inputs into data outputs. ● Data Flow: A curved line shows the flow of data into or out of a process or data store. ● Data Store: A set of parallel lines shows a place for the collection of data items. A data store indicates that the data is stored which can be used at a later stage or by the other processes in a different order. The data store can have an element or group of elements. ● Source or Sink: Source or Sink is an external entity and acts as a source of system inputs or sink of system outputs.

1. Module It represents the process or task of the system. It is of three types as shown in below figure. ● Control Module: A control module branches to more than one sub module. ● Sub Module: Sub Module is a module which is the part (Child) of another module. ● Library Module: Library Module are reusable and invokable from any module. 2. Conditional Call It represents that the control module can select any of the sub modules on the basis of some condition as shown in below figure. 2. Loop (Repetitive call of module) It represents the repetitive execution of a module by the sub module. A curved arrow represents a loop in the module.

- SOFTWARE REQUIREMENT – Microsoft Word, Umbrello
- HARDWARE REQUIREMENT – Computer, Keyboard, Mouse, CPU THEORY: - According to the UML specification a use case diagram is “a diagram that shows the relationships among actors and use cases within a system.” Use case diagrams are often used to: ● Provide an overview of all or part of the usage requirements for a system or organization in the form of an essential model or a business model ● Communicate the scope of a development project ● Model your analysis of your usage requirements in the form of a system use case model Use case models should be developed from the point of view of your project stakeholders and not from the (often technical) point of view of developers. There are guidelines for: ● Use Cases ● Actors ● Relationships ● System Boundary Boxes 1. Use Cases A use case describes a sequence of actions that provide a measurable value to an actor. A use case is drawn as a horizontal ellipse on a UML use case diagram.
- Use Case Names Begin With a Strong Verb
- Name Use Cases Using Domain Terminology
- Place Your Primary Use Cases In The Top-Left Corner Of The Diagram
- Imply Timing Considerations By Stacking Use Cases.
