■Radio personal computer smart phone
 The radio weather information is broadcast by the program name of a "weather report." What can be heard is the 2nd broadcast of NHK. Those who cannot prepare radio need to use the "raziru★raziru" application which can listen to the radio of NHK with a personal computer or a smart phone.

The time when radio is broadcast is 3 times every day…
Between 09:10 and 09:30 (observations at 6:00)
Between 16:00 and 16:20 (observations at 12:00)
Between 22:00 and 22:20 (observations at 18:00)

■Weather chart paper
 The weather cover is what Japan Weather Association made, and is sold in a network, a bookstore, etc.There are two kinds, No. 1 and No. 2, and both prices are about 500 yen in one-volume entering 50 sheet. In addition, No. 1 is a paper for beginners with the table as which the weather for every place other than a weather chart, etc. are filled in.No. 2 is a type as which there is no table as which the weather for every place, etc. are filled in, and it fills in a weather chart directly. The Japanese writing paper of the feature of the map without a table by which part printing is carried out is large.

 If a program starts "it is a weather report at the time of the Meteorological Agency Forecast Department's announcement O moon O day O.It is the weather for every place first... Since it is broadcast as ", time and time are entered in the upper left of a weather chart paper.

 It read "In titizima, winds are the wind force 3 and fine, 1018 hPa, and 24 ℃,blowing from southeast." You write it.If it is as an example, a line is first drawn to southeastern one, the feather of 3 wind force is attached, and a fine sign is written in into a circle. And the lower 2 figure of atmospheric pressure is written to the left of a sign, and temperature is written to the right. When it is hard to write, even if atmospheric pressure and temperature are shifted up and down and it draws them, they are OK.

 Although it is similarly written as the weather for every place, since marine information changes a measurement position every day, latitude and longitude are read out in front of the weather. A circle is written to the position and the weather is written.

 This is read in order of "low pressure" →"front" → "high pressure."

■Low pressure
 A low pressure is read saying "There is a 998-hPa low pressure in 40 degrees north and 140 degrees east, and it is going to northeast at 40 km/h." since x mark is put on the place shown at latitude longitude first of all. And it is written as "L "or "低", an arrow is written in the advanced direction, and speed is written. Since it is sometimes read, saying "it is progressing slowly" or "it having almost stagnated", please take care.

■A typhoon and a tropical cyclone
 How of a typhoon and a tropical cyclone to write it to be a low pressure is almost the same. However, when it was written as "L" or "低" at the time of a low pressure, in the case of - tropical cyclone which is written to be TO number or a stand O number in the case of a typhoon, it is written as "TD" or "熱低".

■Front
 There are four kinds of fronts, and since they differ in a sign, respectively, if they memorize a difference, or they are difficult and a color will be changed and written, it will be easy to do them.

■High pressure
 In the case of a high pressure, it is almost the same as a low pressure, and it puts x mark on the place read with radio, and writes it to be "H" or "高". An arrow is written in the advanced direction and speed is written after that.

 Finally the information on an isobar is read 1 to about two. This explains where latitude longitude passes. It is easy to write that the contour line of a map is imagined and written.
