In the 1990s and early 2000s, comparison of transition strategies of China versus those in Central and Eastern Europe raised controversies in the economic and political science literature. However, differences between China and the countries of the former Soviet bloc in their transition strategies resulted not necessarily from a deliberate political choice but from different initial conditions. Low-income and largely rural China, after its first radical step (de-collectivisation of agriculture in 1978), could move more gradually due to its under-industrialisation and retaining administrative control over the economy. The over-industrialised Central and Eastern Europe (CEE) and former Soviet Union (FSU) countries where the previous command system of economic management spontaneously collapsed at the end of 1980s, did not have such an option. They had to conduct market-oriented reforms as quickly as they could, with all the associated economic and social pain. Regardless of speed and strategy of transition, almost all previously centrally-planned economies, including China, completed building basic foundations of a market system by the early 2000s although the quality of economic and political institutions and policies differ between the sub-regional groups and individual countries.

Focusing on the role of initial condition uncertainty, we use WRF initial perturbation ensemble forecasts to investigate the uncertainty in intensity forecasts of Tropical Cyclone (TC) Rammasun (1409), which is the strongest TC to have made landfall in China during the past 50 years. Forecast results indicate that initial condition uncertainty leads to TC forecast uncertainty, particularly for TC intensity. This uncertainty increases with forecast time, with a more rapid and significant increase after 24 h. The predicted TC develops slowly before 24 h, and at this stage the TC in the member forecasting the strongest final TC is not the strongest among all members. However, after 24 h, the TC in this member strengthens much more than that the TC in other members. The variations in convective instability, precipitation, surface upward heat flux, and surface upward water vapor flux show similar characteristics to the variation in TC intensity, and there is a strong correlation between TC intensity and both the surface upward heat flux and the surface upward water vapor flux. The initial condition differences that result in the maximum intensity difference are smaller than the errors in the analysis system. Differences in initial humidity, and to a lesser extent initial temperature differences, at the surface and at lower heights are the key factors leading to differences in the forecasted TC intensity. These differences in initial humidity and temperature relate to both the overall values and distribution of these parameters. [ABSTRACT FROM AUTHOR]
