Vision and Mission

Vision

Striving for excellence in meteorology at the international level

Missions

Since the TMD missions are designed to contribute to meteorological authorities and administration in the interests of two important goals: the best economic, social, agricultural and industrial products and the protection of lives and property of members of the public were in private sector, and government units to natural disasters, it has been approved to satisfy the following five tasks:
First to provide weather forecasts for the whole country and disaster warnings to publish the representation of the administration and management to respond to natural disasters,
For the second construction of the consciousness of people to natural disasters, so they perform properly on living practices, and reduce the impact of natural disasters through the use of modern technologies in collaboration with computer services,
For the third and a meteorological data center services at the national level for the user in each company,
4th To improve and develop the department manages the research,
5th order to strengthen the international department roles ion Cooperat on meteorology and the environment in order to understand in depth the situation changes in the world.

Weather forecast

Refers to the expected weather conditions in the future. The weather forecast has three main components: The first is to understand the phenomena and processes occurring in the atmosphere Second is the current weather situation. Finally, the ability to mix the two elements above. Together with expectations. Climate change will happen in the future.

Understanding of phenomena and processes occurring in the atmosphere. Derived from observed and recorded. People have watched the weather. The man under the influence of weather and can not be avoided. Therefore it is necessary to know the weather and climate is very dangerous. The observation may explain the causes of air between them, but knowing the weather, there is very little. Compared to the phenomena of the atmosphere by humans are not well understood. Because of meteorology is the study of atmospheric phenomena are linked. Developed with the scientific method was not very long. Previously, many people believe that weather. Current weather conditions are used as input data for the weather. Air. Includes surface air. The higher levels are different heights is important to check the weather, including temperature, air pressure, humidity, wind, clouds and rain the weather in a given area. Weather data will be needed in the region, and the results of air from the environment. This occurs in the atmosphere moves all the time. What’s happening in your area can be moved to the weather predicted to be affected in the region. Therefore, it is necessary to have the test results for exchange of information between countries. To have enough data for weather forecasting. Apart from air, surface and groundwater and the air above. Current weather that allow more accurate predictions. The weather radar and satellite meteorology. Understand the history of the weather. The results of the air. What is to be able to do weather. Is it possible to analyze the results of the air to determine current weather conditions. And unexpected changes in the way the air is underway.
The direction and speed of movement, however. And violence is increasing or decreasing. It is expected that the area is expected to be under the influence of a particular phenomenon. Assigned to then make a forecast on a weather phenomenon with the next.

Step in the forecast.
An important step forward, three steps included. The air to be aware of current weather conditions. Communication to gather information on the weather. And analysis of data for the unexpected. In the analysis of these data. May be a step further. The first step is the result of the weather at all. Both at home and abroad. On a card type paper, such as weather map weather surface. Weather on the floor. Graphics on the air. With standard meteorological symbols. The second step is to analyze the results of the air in the first step. The drawing shows the elements of the definition of science as deeply as if the air pressure at sea level on average. And severity of the wind speed forecast, and direction at different heights on the upper atmosphere. And the screen changes to show a high temperature stability of the atmosphere. This is an important factor in the clouds and rain. The third step is to anticipate change and movement of weather systems, which are analyzed in two steps. With a variety of weather conditions, is the fourth stage, a projection to the space requirements of time and subject. Based on the location and severity of the weather that occurred in the third step. The final step is to send the media to be distributed to the public. And sent to the appropriate authorities for action. Where appropriate. Protection and disaster relief.

The duration of the weather.
The time can be expected for a few hours in advance. The anticipation of what happens in the next few years from now. Can be classified into different types of weather, as long as expected.
1 refers to the current forecast (nowcast), a report in the current climate.
And expected weather conditions for up to 2 hours.
Two very short-term predictions. The forecast for the period up to 12 hours.
3 Short term forecast is the forecast for the period from 12 hours to 3 days.
4 medium-term weather forecast is for a period of more than 3 days.
For 10 days.
5 to predict the long term. The forecast for the period from 10 to 30 days.
In general, it is expected that the average of meteorological variables at the time.
Is different from the average climate.
6 The long-term forecasts. The forecasts range from 30 days to 2 years, divided into three types.
6.1 The expected monthly average, expected weather variables.
Meanwhile, the deviations from the mean geographical vacuum, however.
6.2 The prospect of three months. It is expected that the average values ​​of variables in the season.
Science in the region. The deviations from the average climate, however.
6.3 The expectations for the season. The average forecast of the season that is of value.
How does the average climate.
7 climate prediction. The forecast for the period, divided into more than two years.
7.1 Prediction of climate variability. Forecasts in terms of changes
Normal up to a year for several decades.
7.2 The climate prediction is a prediction of future climate.
Two words. Caused by natural and human activities.

As the weather forecast.
What is the probability with the direction and speed of movement of weather systems that can be formed. Expect that future systems will be in any position over time without switching speed, direction and intensity. This method is often used for the forecast of rain in less than half an hour. Forecast by the climate is estimated by the average of a climate static for many years, this approach works well if the weather is close to the normal season, it is not often used for the forecast period. Weather forecast with the computer is a computer calculation of the change of variables involved. With weather conditions. With the numerical simulation (numerical model), the atmosphere and the earth. Mathematical equations with a delicate and complex, the limitations of this approach is the model. Not exhaustive in nature, that meteorologists are practical methods often used together in many ways, if any. For the most accurate forecasts.

Errors in weather forecasting. Although the current weather forecasts rapid progress. But the weather forecast. Be completed without error. It is not possible. The three main sources of error in the forecast included an initial overview of various weather phenomena, the second stream and the atmosphere is changing. Weather stations are few and very far. And make it the only time, as is every 3 hours, not knowing the real state of the atmosphere. Is it because of the weather conditions are not fully developed. It is impossible to predict all the details are correct. Finally. The nature of the processes occurring in the atmosphere. Extremely sensitive complex. Phenomena that are small or occur, not the short term and may be required to detect the air. May cause changes in the weather is much more to come in time. This will affect the forecast error dramatically. Finally, because this is a limitation especially in weather forecasting. Is reduced for this reason, weather forecasts by the policy. Time is the time for a short time, it is more accurate than forecasts for longer periods. The tropical climate in the world such as Thailand. It is more difficult than expected in the hot and cold due to three main reasons.
First, knowledge about the progress of meteorology, tropical meteorology, as in the high latitudes.
Since research on meteorology in the tropics, much less.
Second, the weather stations in the tropics, less in hot and cold.
The results are less
Third, the weather in high latitudes is much larger.
It is caused by different air masses meet. Can be easily recognized.
The rain caused the collision is over 1,000 km.
While the weather in the tropics, the little ones. It is not caused.
The differences in air mass. Rain is a small space.

What is the best time to travel to Thailand?

Normally people say that is not defined stations in Thailand and three seasons in Thailand are “warm”, “strong” and “hot.” This is not entirely true that Thailand is also blessed with a breeze in winter and the weather can be cool enough to be enjoyable. However, if you travel to Thailand to plan and prepare for the searing heat during the year.

Describe the climate in Thailand can best be described as tropical and humid. Parts of the country is dominated by the monsoon. The hottest months of the year, between April and May, where the temperature can rise to about 37-40 ° C, resulting in numerous complaints from locals.

In general, the best time to visit Thailand from November to February when the northeast monsoon which blows cold, dry air, which serves as a respite from the heat. In winter, temperatures vary between 18 ° C to 32 º C in Bangkok, while in the north and northeast Thailand, temperatures can be quite cold, with temperatures in the morning just 8 º C to 12 º C , with the occasional 20 ° C during the day. Nights can be particularly cold and high altitude, temperatures can drop below zero and no.

The summer, or hot and dry season from March to June temperatures at this time in Bangkok average around 34 º C, but often up to 40 º C and a humidity of 75%.

Try to avoid April, unless you’re constantly immersed in the ocean because it is the hottest month across the country plan.

From July to October is the rainy season, when most annual rainfall is collected in Thailand. Humidity on average just under 90%, with average temperatures of 29 º C in Bangkok.

The monsoon comes, when the wind direction changes, bringing dry weather in the Northeast. At best this season so unpredictable and the constant rain, the rain will describe the way you want. The middle months of the season can be especially intense rain in the north.

Thailand’s climate is tropical monsoon and is determined by the climate of Thailand is generally hot and humid in most countries controlled most of the year. While Thailand is divided into stations, usually in summer, the season of cold and rainy season are, in fact, is relatively warm throughout the year. The weather in central Europe, north and northeast of Thailand (provinces of the interior) is determined by three seasons, while the coastal regions of southern Thailand have only two, to understand what the climate in Thailand and quite easy to plan a trip .

In the interior provinces of Thailand, the seasons are clearly defined: Between November and May, the time the season in a cool, dry and hot season is from November to February and March to May, respectively.

The season runs for another in the rainy season from May to November and is expected monsoon, where rainfall in most of the time in Thailand is dominated by the heaviest.

The best time to most of Thailand to visit is between November and February, because it rains least and is not too hot. This period is also high season in Thailand during the holidays, such as Loi Krathong.

If you are in the northern provinces, the hot season (March to May) and plan the start of the rainy season focused (June-July) are not too bad, because the temperatures are moderate in highlands. The northeast and central Thailand, on the contrary, it is best to avoid March to May, when temperatures exceed 40 ° C. Since temperatures in the south you can this year (because it is closer to Ecuador), the beaches and islands of southern Thailand is a good choice for a break when the rest of Thailand is miserably hot.

The main tourist season in Thailand runs from November through March, with secondary peaks in July and August, if you escape the crowds and enjoy a reduced price must travel for months less crowded (usually April to June, September and October).

Although the rainy season (around July-October) received a bad reputation, there are some cooler temperatures bonus, in general, tourists are fewer and the landscape is lush and green. Depending on the region and the months, could the rain in the afternoon hour. October tends, however, the wettest month.
