What is a synoptic weather map used for?
A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.

noun. a chart showing the distribution of meteorological conditions over a wide region at a given moment.
What are the features of a synoptic chart?
Synoptic charts consist of curved lines drawn on a geographical map in such a way as to indicate weather features. The curve lines are known as isobars (lines of equal pressure) drawn around depressions (lows) and anticyclones (highs). Air moves from high to low pressure along a gradient.
What is the function of weather chart?
Weather charts can describe the weather conditions on ground, or at high altitudes, and are the basis for the creation of weather forecast maps.

What is a synoptic charts Why do we use it for passage plan?
The synoptic chart is similar to a topographical chart where it shows the variation in atmospheric pressure over the Earth's surface. We must remember, that it is a fairly simplistic representation of past, present, and future locations of weather systems, but it does provide an extremely useful guide.

How are synoptic weather maps generated?
Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover onto a geographical map to help find synoptic scale features such as weather fronts.
What is the importance of studying synoptic meteorology?
Synoptic meteorology has traditionally been concerned with the analysis and prediction of large-scale weather systems, such as extratropical cyclones and their associated fronts and jet streams. An important aim of synoptic training is to acquaint the student with the structure and behavior of the real atmosphere.
What is the importance of ocean passage of the world?
Ocean Passages for the World (NP136) supports the planning of deep-sea voyages on most major routes, with details of weather, currents, ice hazards and distances between major ports.
What is the main purpose of voyage planning?
A voyage plan (or passage plan) is a comprehensive, berth to berth guide, developed and used by a vessel's bridge team to determine the most favorable route, to identify potential problems or hazards along the route, and to adopt bridge management practices to ensure the vessel's safe passage.
How do you make a synoptic chart?
The first stage in preparing a synoptic chart is to chart the position of each meteorological station. These are marked by a small circle. The weather report for each station is then plotted in and around the circle. Elements like temperature and pressure are entered as plain figures.

What are the benefits of exploring the ocean?
Information from ocean exploration can help us understand how we are affecting and being affected by changes in Earth's environment, including changes in weather and climate. Insights from ocean exploration can help us better understand and respond to earthquakes, tsunamis, and other hazards.
What is the purpose of Oceanography?
It regulates Earth's climate, plays a critical role in the hydrological cycle, sustains a large portion of Earth's biodiversity, supplies food and mineral resources, constitutes an important medium of national defense, provides an inexpensive means of transportation, is the final destination of many waste products, is …
What are the 4 four stages of voyage planning and its purposes?
There are four stages of Voyage Planning that are, Appraisal, Planning, Execution and Monitoring that logically follow each other. An appraisal of all information available must be made before detailed plans can be drawn up and a plan must be in existence before tactics for its execution can be decided upon.
What is the purpose of check route function in ECDIS?
Check Route Function: The navigating officer should make use of the check route function after passage planning to ensure that vessel will not encounter navigational hazards on the planned route. These hazards would be mainly pertaining to grounding dangers, crossing TSS line / boundary and user defined alarms.
What is synoptic assessment?
Synoptic assessment refers to the assessment of students' understanding of the links between the different elements of a subject. Despite its ability to promote a holistic delivery of the curriculum and deep learning, it is currently an under-researched topic in the field of educational assessment.
What is an example of synoptic?
The definition of synoptic is something that makes up a brief summary or shortened version. An example of synoptic is an outline of a scientific research paper that gives key points; a synoptic outline. Of, or relating to a synopsis. Of or constituting a synopsis; presenting a general view or summary.
How do we map the ocean floor before the discovery of advanced technology?
The first primitive maps of the sea floor came from “soundings” which involved lowering weighted lines into the water and noting when the tension on the line slackened. The depth was then measured by the amount of line that had payed out.
How can technology make underwater exploration easier?
Today, buoys and water column samplers are used to monitor sea surface conditions and water quality factors, coring devices collect sediment samples, sonar helps create maps of the seafloor, and remotely operated vehicles (ROVs) allow us to safely and efficiently explore all parts of the ocean.
How do Oceanographers measure the salinity of ocean water?
Oceanographers measure the salinity of ocean water by using a hydrometer a hydrometer set a chemical test kit or a salinometer. A hydrometer is a quick test tool used in aquariums and it works by reading the water density. Higher dissolved salts result in higher density.
How does oceanography help the environment?
The ocean has a great effect on the world's climate because the sea stores so much heat – oceanographers can help to predict future changes in the temperature of the planet, and also to give warning of sea level changes, which could devastate low lying countries and coral reefs.
What is the difference between passage planning and voyage planning?
A voyage extends from berth to berth. Passage (or “sea passage”) is the phase of a voyage between the seaward limits of pilotage waters at the ports or places of departure and destination, usually denoted by “Full away on passage” and “End of passage” entries in a bridge movement book.
What is the important function of ECDIS in regard to the safety of navigation?
The ECDIS utilises the feature of the Global Positioning System (GPS) to successfully pinpoint the navigational points. It also has to be noted that the ECDIS adheres to the stipulations set by the International Maritime Organisation, and thus it adds to the trustworthiness of the electronic chart system.
What is docking mode in ECDIS?
The Docking option is an additional software module that can be added to the K-Bridge ECDIS and Planning Station applications. Information about the vessel such as the heading and past and predicted ship positions are displayed on the chart. At the same time a panel next to the chart provides relevant data for docking.
