Atmospheric and oceanic phenomena can vary on intraseasonal timescales. Intraseasonal variability provides a bridge between weather variability, which usually occurs on timescales of a few days, and seasonal variability, which occurs with a period of >60 days. Understanding these intraseasonal variations is of great interest to research and forecast communities as this may help to develop and improve the skills in predicting oceanic and atmospheric fields a few weeks ahead. The intraseasonal variability of sea level can have a crucial impact on the coastal flooding risk as it may alter the occurrence of extreme sea level events when superimposing on other factors under extreme conditions.The Intraseasonal Oscillation (ISO) is one of the dominant modes of climate variability especially in the tropics. It has significant seasonality in frequency, intensity, location, and propagation (Hartmann et al., 1992;

The outbreak of the new crown pneumonia epidemic has brought impact and changes to the lives of all people. It also puts forward higher requirements on the production capacity and creativity of Chinese pharmaceutical industry. Under the epidemic, the development of Chinese pharmaceutical industry is facing good opportunities and ushered in bright prospects. But it is undeniable that there are still some problems and challenges that need to be resolved. A simple analysis of the current situation and development opportunities of Chinese pharmaceutical industry is carried out. Some problems and challenges in its development process are explored, and some relevant countermeasures are put forward to promote the healthy and rapid development of Chinese pharmaceutical industry.

Ginseng is an important cash crop. The long-term continuous cropping of ginseng causes the imbalance of soil environment and the exacerbation of soil-borne diseases, which affects the healthy development of ginseng industry. In this study, ginseng continuous cropping soil was treated with microbial inocula using broad-spectrum biocontrol microbial strain Frankia F1. Wheat straw, rice straw and corn straw were the best carrier materials for microbial inoculum. After treatment with microbial inoculum prepared with corn straw biochar, the soil pH value, organic matter, total nitrogen, available nitrogen, available phosphorus, and available potassium were increased by 11.18%, 55.43%, 33.07%, 26.70%, 16.40%, and 9.10%, the activities of soil urease, catalase and sucrase increased by 52.73%, 16.80% and 43.80%, respectively. A Metagenomics showed that after the application of microbial inoculum prepared with corn straw biochar, soil microbial OTUs, Chao1 index, Shannon index, and Simpson index increased by 19.86%, 16.05%, 28.83%, and 3.16%, respectively. Three classes (Alphaproteobacteria, Gammaproteobacteria and Sphingobacteria) were the dominant bacteria in ginseng soil, and their abundance increased by 7.87%, 9.81% and 1.24%, respectively, after treatment with microbial inoculum with corn straw biochar. Results indicated that the most effective treatment in ginseng soil would be the combined application of corn straw biochar and Frankia F1.
