    Each country needs to decide on its priorities. Panama has had about 1,400 deaths from Covid-19 per million population. A similar death toll in Thailand would mean almost 100,000 deaths instead of the current 94. I personally agree that saving almost 100,000 lives of your citizens is worth restrictions on tourism. Others might have a different sense of the priorities.

    Thailand has 16 times as many people as Panama. 16 times 1400 is about 22000 deaths. Don't exagerate!

  2. This has nothing to do with typhoon Kammuri. At the time of the heavy rain in Narathiwat the typhoon was far east of the Philippines, at that moment not even affecting the weather in the Philippines. The heavy rain is a normal occurrence at the Thai east coast in their rainy season (October to January), also called the NE monsoon.

    In most years it is more rainy than this year.

  3. I have a solar power installation with back-up batteries. The available solar radiation in Thailand is about 5 kWh per day per square meter. The efficiency of the solar panels is not much more than 10%, so you can rely on 0,5 kWh per day per square meter of solar panels.

    So you must calculate how much electricty your pumps will be using per day (in kWh) and then multiply by 2 to find the needed area of solar panels.

    Protect the installation from lightning strikes.

    No mention of what Naga refers to. 

    It is named after Naga mountain that towers over Khlong Muang. There is a nice and easy mountain trail going to the top at 500 m altitude. Many festival attendants make that trip to enjoy the magnificent view. Naga (pronounce Naak) is some sea goddess.

    Right, can you show me a website where they explain how frost/rhyme/hoarscope can happen on grass when the airtemp is 1 celcius?

     

    The dutch websites all explain it when the temp is under zero and that i understand. I don';t understand how grass can get below zero when the air around it is 1 celcius.

     

     

    I try to explain again: At night the earth cools by outgoing (infrared) radiation. That goes for the earth surface and also by objects like plants and cars. The atmosphere cools only a little bit by this outgoing radiation. The air cools most by contact with the cold earth surface and the objects. That is why the air at a clear night with little wind is coldest near the surface. The air at 1,5 m altitude, where the air temperature is measured, is warmer than the surface. So it is fairly common to see air temperatures a few degrees above zero while your car windows are covered with rime.

    My transliteration handbook cites "kai" as an egg.... and "gai" as a chicken..... not sure which came first, kai or gai.... but ThaiVisa once agains gets the basic spelling incorrect.....

    The spelling "kai" is better than "gai" because the hard "g" sound does not exist in the Thai language. You just have to remember that the "k" in many languages is unaspirated (all Romanic languages and Dutch). If you want the aspirated version like the word for "egg" you just add "h".

    k is not aspirated and kh is aspirated. Not difficult to remember, I guess. The same goes for t and th and for p and ph.

    Transliteration to English writing is difficult as the English spelling is even inadequate for the English language too.
