Show moreThe current analyses of T and Q over the traditionally data void regions heavily rely on satellite radiances and in cloudy situations where satellite radiances are difficult to use. In such cases, satellite wind is the major data resource and the analyses may be generally questionable. The large uncertainty of the analyses makes initialization of forecasts including cyclones and hurricanes difficulty. Study of the weather and climate related to these regions also suffers from the large uncertainty of the analyses. There is a significant need to improve the analyses. Show less
