Sunshine and Rain Weather Forecast for Asian, Middle Eastern and East African Regions


Weather Forecasting using Satellite Weather Images

The Satellite Weather maps provided here are from the High Technology Satellite Weather Images of METEOSAT-7 Weather Satellite, by courtesy of Cooperative Institute for Meteorological Satellite Studies / University of Wisconsin-Madison Space Science and Engineering Center.

The Satellite Weather Maps provided by Meteosat-7 shows majority of the areas of India, Sri Lanka, Pakistan, Maldives, Nepal, Bhutan, Bangladesh, Burma, Thailand, Malaysia, Cambodia, Vietnam, Laos, Indonesia, UAE, Saudi Arabia, Egypt, Yemen, Eritrea, Ethiopia, Kenya, Tanzania, Madagascar , Mozambique and the Indian Ocean. Today's Weather and Weather Forecast patterns can be obtained from these Satellite Weather map images.

Based on the example map provided with countries marked, the visitor can easily identify the area he is searching for satellite weather information.

A basic knowledge on how to identify the rain clouds on a map showing Asian, Middle East and East Africa and the Indian Ocean by the Meteosat-7, will enable the visitor to know exact weather conditions of the region at the moment and the possible weather pattern for the next day or more.

Example maps with readings are given for easy understanding. Anyone like to study the topic in detail can visit the Web sites of University of Wisconsin-Madison Space Science and Engineering Center which opens up for Weather maps linked here.

These satellite weather maps gets updated once in every three hours.

If you are unfamiliar with Satellite Weather maps, the following example reading may be of help to identify the rain clouds on the map.

Example reading from an enlarged Sri Lanka map obtained from a Satellite Weather Image

The enlarged Sri Lanka map can be seen here with India in the north west direction and blue coloured Indian Ocean surrounding the island.The cloud like formation appearing in white is the probable rain clouds covering the south east section of the island. A bigger cloud formation is already at the southern section of the island so the rain cloud activity will be there for the southern part of the island for few more hours. The island is 268 miles lengthwise and 139 miles across at it's maximum width. We can know the wind speeds from the data maps provided and can assume roughly how much time a rain cloud covers the territory or the approach of a rain cloud and also a rough idea of the rain cloud size, compared to the size of the island.

Upper Level Winds from Meteosat-7

Atmospheric Motion Vectors (AMV) indicate winds in Upper layers of the atmosphere. The photo shows wind effects of 3 layers of the atmosphere by the three colours used. The blue colour is for winds in the region [100-250 mb pressure] , corresponding to 45000 feet and 34000 feet above sea level. The yellow colour is for winds in the region [251-350 mb pressure] corresponding to 34000 feet and 26500 feet above sea level. The green colour is for winds in the region [351-500 mb pressure] corresponding to 26500 feet and 18000 feet above sea level. These are helpful to notice concentrated Upper Level Divergence of the Winds.

Lower Level Winds from Meteosat-7

Atmospheric Motion Vectors (AMV) indicate winds in Lower layers of the atmosphere. The photo shows wind effects of 3 layers of the atmosphere by the three colours used.The blue colour is for winds in the region [400-599 mb pressure] , corresponding to 20000 feet and 14000 feet above sea level. The yellow colour is for winds in the region [600-799 mb pressure] corresponding to 14000 feet and 6000 feet above sea level. The green colour is for winds in the region [800-950 mb pressure] corresponding to 6000 feet and 1500 feet above sea level .These are helpful to notice concentrated Lower Level Convergence of the Winds.

Wind Shear (color)

Wind Shear charts come in handy when there is Tropical Cyclone activity in the region. Wind Shear is the net result of the change of speed or direction of wind speed along a straight route of its travel and the result is given in Knots.Here the Upper Wind is taken at a range of 150-300 mb range which corresponds to an average of about 40,000 feet above sea level and the Lower Wind is taken at a range of 700-925 mb range which corresponds to an average of about 5000 feet above sea level. Low Wind Shear Values of around 5 knots are bad if they appear near Cyclone or Hurricane activity, since low values can intensify the activity of the Cyclone. Higher figures like 40 Knots or more will dissipate the Hurricanes power and makes it less destructive. The Coloured Bar at the right indicates the corresponding Wind Shear values in Knots, which in turn shows Hi and Lo Wind Shear Values in the whole region.

Looking carefully at the Chart will show you the land mass demarcated in White which shows, Sri Lanka, India, South East region ,the Gulf and a part of Africa. Yellow contours indicate the corresponding numerical value in Knots of Wind Shear in that area.The direction of the Shear is indicated by the arrow directions of the Pink lines. Normally it is an indication of the Upper Level wind direction also.

Wind Shear Tendency

This map indicates the trend of the Wind Shear valves, by indicting in contours of White solid lines, the trend of the incremental values in Knots and by Blue dashed lines, the tendency of decreasing values of the Wind Shear in Knots.

Upper Level Divergence
150-300mb layer mean

Upper Level Divergence

This map shows the Upper level of the troposphere , around 40,000 feet up from the sea level. Moving away from a common point to different other directions can be explained as Divergence. The Wind coming up from the Lower Level Convergence rushes up and In the Upper layer, they move away to other directions. If there are concentrated rings like contours, which also in the same placement of a concentrated Lower Level Convergence, then there is a possibility of a formation of a Tropical Storm or a Hurricane. Increasing values are given in solid Yellow contours and decreasing values are given in dashed Yellow contour lines.

Lower Level Convergence
850-925mb layer mean

Lower Level Convergence

This map shows the Lower level of the troposphere , around 5000 feet up from the sea level. Coming closer to a common point can be explained simply as Convergence. The air at lower level gets concentrated to a smaller area and moves upwards in this instance. In the Lower layer , if there are concentrated rings like contours, which also in the same placement of a concentrated Upper Level Divergence, then there is a possibility of a formation of a Tropical Storm or a Hurricane. Increasing values are given in solid Blue contours and decreasing values are given in dashed Blue contour lines.

Kalpana-1 IR Image

NOAA satellites use Zulu Time or Coordinated Universal Time (UTC) as their time reference. The satellite images that appear on NOAA's Web sites are stamped in Zulu time. Add 5 Hours and 30 Minutes to the stamped Zulu Time to get the Sri Lankan time of the image. (There is a Z behind the 24 hour time stamp of Kalpana-1 images.)
